Mate! What is your A/F ratio? I think you are running too rich or your tunner did not do a good job. I have the same set up but was running mega rich. Power was about the same as yours and my tunner took off 10 - 12% of the fuel through out the rev range and Whala.........power jumped to 176rwkw with only 10psi of boost on stock turbo.

hi flow cat yes, knn filter, split fire coil packs,

man if i post up my dyno run video the thing was making flames at the back

the tuner said i need a fuel regulator as the fuel pump is putting in too much fuel

where on the dyno sheet does it tell ur afr rations... i'll zoom in on everytihng i can find n upload pics

Zas,

Are you using stock fuel reg? If so, you do not need the walbro fuel pump for under 200rwkw. Put back your stock fuel pump with your stock fuel regulator and tune it. You will get the power everyone is getting for that setup. If you want to go more then 200rwkw, then get your turbo hiflow, walbro fuel pump with stock fuel reg and a proper tune, you will be able to get close to 230rwkw.

yes i am using a stock fuel regulator

the tuner advised me to get a after market fuel regulator to make it better

though... 230 ? with just a turbo.. jumping anoth 77 kw man dats a big jump???

no i ahve a 3 inch dump, hi flow cat, 3.5 inch catback exhaust with a large blits front mount, electronic profec b, apexi neo, Knn air filter, SPlitfires, Walbro fuel pump

stock fuel regulator , stock turbo and a small green haired troll

yeah i was told that my fuel pump was maxed out too. car was runnning was rich like 9:1 ratio. ridiciulous. creatd leaned it up to a safe 12:1 and from 150ish rwk i made 182 just from the a/f. and 10 psi boost. i have a hiflow tho. who tuned your car?

yeah his saying that theres too much fuel pressure and he cant tune it down?

need a fuel pressure regulator ....

thats onli 10 psi i got this score from boosting up .9 pounds

is motor racing....they did few drift cars in the hot fours....

Sorry, thats incorrect.

Its a very very wise idea to upgrade the fuel pump over stock.

Time and time again you see people here asking why they are leaning out, and each time its the stock fuel pump.

Thats shocking advise from your tuner mate. Unless the factory fuel reg is stuffed, which going by the dyno graph its fine, then fair enough.

But the stock reg is perfect for the task.

A fuel reg will not "give" you power unless you have maxed out the stock injectors, which wont occur until around 230-240rwkw.

And you dont have that power, you need a bigger turbo for a start.

I also reckon the tune you have whilst conservative... its a little "too" conservative, ie. its way to rich, and this is evident by the car blowing flames.

You dont need 11:1 AFR's, its too rich. 11.5-12:1 is what your after and even thats not leaning on the car.

In all honesty, the tune is crap. The advice your being given, is also crap.

I would be looking for a refund and finding a new tuner.

cheers

Also .9 bar = too much boost on the stock turbo.

There is a risk you'll blow it.

Im with nismoid. That tune is average. and the advise your being given is poor as well

Leave the pump in it, leave the stock fuel reg drop the boost slightly to prolong the turbo's life and have it tunned properly.

At that sort of mod level id be tunning it to roughly 12.2 :1 and it will make very decent power, I know you only have a neo so there is only basic tunning to do but honestly that AFR graph looks like something my apprentice could knock out.

he couldnt get it any higher he sed?

with boosting at 0.9 pounds he was running it max to 153 .5

so nismoids adice being that i dont need a fuel regulator i need a new tuner lol

whata waste of 500 bucks and new platinum plugs ( to which he sed my coppers where shitted on ) fair nuff...

Cant get what any higher? the power?

Thats because they clearly don't know how to tune. 11:1 AFR's are silly and that's what's causing your poor power.

The car will also feel quite lazy as well. You'll be amazed what a good tune feels like

paulr33 means somewhere else, only because if the tuner calls that being "tuned"... then they have done an incredibly bad job, which isn't cool.

As it looks like they have not "tuned" it at all, well... i lie... It looks like the made changes to the tune, but all the wrong ones and nothing right :)

Also plati plugs are a waste of money.

dollar for dollar coppers are far better, also work just as well, if not better

    • Had a go at the stuck crush tube this afternoon. Tried things like grips and a chain wrench first but wouldn't just twist straight off. So got to work with a drill. Started small and kept a depth stop on to make sure I didn't drill into the bolt. Made a line of drill holes all the way up and enlarged them. Then a combination of chisel and Dremel to split it all the way up. Levered the split to get oil in there and eventually it gave a bit while levering. Worked it back and forth with loads more oil till it was spinning freely, then with grips I could work it downwards and off. And no significant damage to the bolt (not by me anyway - just the 27 years of rust)
    • Well, I'm tired. I'm tired because about 4PM yesterday, before today's appointment someone immediately bought my bumper. They couldn't get it any other day as they're on the way back to NSW. So I had to do that big GTR conversion I had been planning. Unfortunately, the information on SAU about what you need and how this is done is incomplete. So what should be a simple bolt on affair, yeah, it's not. Did you know if you use all GTR items the bonnet won't close? This little manuever sent me into about 1am the night before trying to dodge a way to get it closed. I will have to revisit this in the next few days  - or maybe not, I may let a body shop figure it out. It all needs to come up and my motivation to pull the bumper off is low. It also seems to hit things in the bay where the GTT bonnet didn't. Yes I used 100% new OEM GTR items. Today, I had the joy of driving to the dyno looking like this: Given I had roughed in the fuel and given sensible but pretty conservative timing, I didn't really bet on having the car drive out any real difference than when it drove in. Sadly due to a miscommunication and laptop fun and games (and almost bricking the dongle, prayers and firmware updates indeed), I ended up using HP Tuner credits to licence the car that was already licenced. So in the end my laptop was used. It turns out my butt dyno is still well calibrated after all this time. The 325kw was on 74% Ethanol, the 313kw line was on 98. The other line is the 'before' line which was 281kw. While the numbers are pretty low, they're pretty in line with what you'd expect. Even if US dynos bump the whole result up about 50KW, gaining 10-15% is similar gains.  The curve of the cam is pretty much spot on with what was discussed as well. All this said, it still feels bad to not see the number you secretly want to see. Even if the car drove great beforehand, and I knew pretty confidently the car would drive out much the same way it drove in due to the nature of a wellish dialled in LS1 not gaining much if anything at all from being tuned from where it was. As expected, the car isn't particularly sensitive to running it at anywhere between 12.0 and 13.0 - And the initial timing at 20deg and 12.0 made 308KW. So 3 degrees of timing, and leaning it out to 12.7 for 5kw, anything above stopped giving any benefit until E85 (which has an additional 2 deg as before). Car itself behaved entirely fine. I found out that 100C = 1.15V! IAT at about 7pm was 19C. I might mess with the bonnet mounting.. but given the REO NEEDS TO BE CHOPPED TO FIT A GTR BAR this is possibly something I may leave gathering (more) dust until it returns to paint jail.
    • It sounds farrrrrrr too cold at your place Duncan... Here I was thinking our 10 degrees overnight is getting cold...
    • oh yeah, reminded this morning....bin lids frozen shut too
