Tune Disappointment :(

[levinboy]

Hey all, had my power fc pro installed and tuned today with tomei cam gears on my 33gtr, was excited to go and pick her up but...

result was only 201 atwkw, when i first bought the car i dynoed it and made 203.5atwkw

Is it just the tune that sucks, should i go back to the tuner and ask questions or go to a different tuner??

car is stock other then kakimoto exhaust (3 and abit inch) from dumps back high flow cat and boost restrictor removed

Does it feel better? Thats all that matters, different dynos can give vastly different readings, what was the difference between the first run on the current tuners dyno and the end result, thats far more important than a figure it got else where!

Didnt get the first run to compare as i dropped it off early,would it be worth going to a different dyno and having a run??

Feels more torquey and pulls harder (i think)

Had a look throught the RB26 dyno thread and there is a 33GTR with similar mods and has 264kw

WHat boost are you running?

[R31Nismoid]

Well 264 is probably a bit optimistic... depends on the dyno maybe +/- 15-20rwkw.

240rwkw would sound about right for the mod level.

As stated already - does it feel better? You should feel a noticeable difference. If so, then is mission accomplished IMO.

You don't wanna push stock turbos too hard anyway

[snozzle]

hard to judge unless you tell us what mods you have?? also what did your tuner say? did he have any comments?

Thats all that matters mate, Dyno numbers are just numbers, Ramp rates, incorrect intake temps ect all make a difference, If you really want go and find a place that will give a better number....but it wont make it any faster

[levinboy]

WHat boost are you running?

Boost is at around 14PSI

Well 264 is probably a bit optimistic... depends on the dyno maybe +/- 15-20rwkw.

240rwkw would sound about right for the mod level.

I was hoping for around the 230 mark

only difference i believe i can feel is the torque, print out stated 588Nm

you'd want more torque anyways, more torque the faster you get to the speed you want to get to.

Mods stated in first post

Power fc

cam gears

kakimoto 3 and abit inch exhaust from dumps back

high flow metal cat

stock everything else

Splitfire coil packs

Exactly, me and a mate were stuffing around with my stock turboed R33, and made 450ish rwkws at 10psi lol

Helps when you stick the intake temp probe on the turbine housing LOL

My old 32 made 750rwkw via a similar method lol

Did you use a reputable tuner? And have you discussed the tune with them?

Around 250rwkw used to be average for Racepace with similar mods to what you have, but it was +/- 10kw. Also dyno's do differ a little so you can get different power levels on different days / places

[snozzle]

my car made 232kw on 0.9bar on the stock ecu with stock boost control solenoid, everything was stock besides tomei dump pipes and full exhaust

after i got it tuned with a pfc it made 366hp on 1 bar at all 4 hubs so around 260awkw? that was still with no cam gears, will get cam gears installed before the next tune

Used a reputable tuner here in sydney, going to geelong for 3months starting in June might go see racepace while im down there, always admired their work

Can you post up the dyno so we can investigate? Would be good to see the boost graph too.

[Trozzle]

I'd honestly just get a second opinion on the dyno...get 2 or so runs on a completely different dyno by another reputable workshop just to see power output. I reckon it's just a low reading dyno.

[paulr33]

as long as it feels quicker and makes more torque thats all the matters really

besides you have launch control so learn how to use that and away you go

its great beating cars when you quote less power, it means you are a better driver

ie if you can beat most cars with 200awkw GTR your a good driver

[Trozzle]

exactly. "Seat of the pants" dyno is the one that matters. If it feels quick and responsive, and you enjoy driving it, then that's what you paid for.

Top end power is just a number. Peak power is always very close to redline on a stock setup. How often are you there? Depending on tune, you can have a very responsive car but effectively very low peak power. An example will be my GTS-T come Friday. Currently it's making 284.9rwkw on 15psi. I have swapped the actuator, so I will be getting it retuned on 17/18psi on Friday. I have asked the tuner to go easy up the top of the rev range, and mainly tune for response and torque when the boost comes on...I told him that I don't give two shits if it makes the exact same peak power, it's all about how it feels when it comes on and sticks me to the seat
