Tomei Cams Making Car Rough?

[AngryRB]

This may have been covered before but i need some clarification,

I have tomei cams 256 8.5lift, car has been tuned and ive been assured by tuner that the mixtures are fine and he showed me that that changing the mixture made no difference. Im ruling out vacum leaks cause it seems to behave under throttle, but at light throttle it wants to jerk and under 2000rpm it will be jerky if you dont put the hammer down.

is this just normal with these cams or are my injectors dripping?

With these cams will i foul up my plugs if im doing alot of slow off boost/idling style driving?

I noticed after a squirted it in second and came on full boost, then pulled up at drive way it was behaving itself , and just 5mins before it was stalling on me....

any thoughts?

[Dose Pipe Sutututu]

that doesn't sound right

longer duration cams will need a tad higher idle & not stoich at idle (maybe stoich is possible if RPM high enough).

Sounds like he hasn't set the throttle enrichment properly, time to find a new tuner.

definetly in the tune. i have same cams without any issue

Take the drive down the coast to DVS JEZ

Get him to tune your car

Win win

Im getting tired of going thru tuners

tonight it was going weird too, started hunting like the power fc was reset or somthing, then came good, also noticed a massive cloud of smoke after a squirt in second, was enough to fill the street up, thats the second time ive noticed this...

I tell ya im getting so annoyed with tuners and not getting the results $$$ has been spend here...

Maybe when i go E85 ill just take the drive and give him a go, cant do any worse surely..

Can pretty much guarantee you'd end up happy if DVS JEZ tuned it, take a look at all the results from his tunes. I'd get him to tune my Z32 when its done, but i'm doing the unigroup tuning course and want to do it myself

[AngryRB]

gees thats like a 8hr drive, hope i get some kind of discount, and that it doesnt some how blow up on the dyno, cause dam thats a long long way to get home,

id end up just torching the car like on Monster Garage, jess james style hahaha

Well we already established earlier you probably need to visit a better tuner...

Why don't you go to EFI, they are in QLD and have been doing good work

[Old Booster]

Who's your tuner? PM me if you do not wish to name him publicly.

well at the risk of getting flamed, i did originally go to ERD for my dump and it ended up with a 4week wait, and not his fault he was very busy and i got impatient and decided to pick it up, anyway, the dump was rubbing on the body so it wasnt right, and no hanger to support it and i got the shits with the whole thing, now EFI is part of that workshop so should i really take it back there... ???? i dont know..

seems like a bad experience to me.

[AngryRB]

I really dont know if this is my tuners fault, hes tuned many many high horsepower cars, one GTR on ignition DVD which put out 850HP and without proof i dont want to give him a bad name.. i think hes a good bloke, a tuner can only do what they can with what there given.

so is it the consensus that its the tuner??? im starting to think that the whole laggy turbo response could even be these cams, what do more extreme cams do? is it possible that i was mistakenly given more extreme cams that are causing massive duration??

[boostn0199]

I had the same thing when I installed the cams, went away after the tune, but in saying that it was also partly from a dying CAS.

[AngryRB]

my cas is brand new so maybe that just highlights the tune again, every time i pull up at some traffic lights people thing im ready for a drag lol... pretty funny. its similar to victa bray's burn out chevvy haha rah rah rah rah cant complain when the hammer is down though, in second gear on a bar, the back end was wanting to turn 180 degrees, bit scary.

maybe i should just use it like a burn out car and forget street driving

A second tuners opinion would be a good idea I think, regardless of how nice of a person the original tuner is. Different approach to tuning it might yield better results or might not, but you won't know until you take it elsewhere.

[AngryRB]

thats a good point, maybe they can just do a quick run and look at the maps , its hard to know who to trust with tuning, they all spin there stories, im thinking DVS is the go, seems to have alot of credit on these forums.

[Manuel Kasko]

He spent something stupid like 13 hours on a Sunday fixing all the shit that was wrong with my car. Even got me dinner and lunch haha

If your down for the drive man it wouldn't hurt.

Then again 8 hours is a long time lol

[AngryRB]

better be worth it or ill be bordering psycho lol... bring out a shot gun or somthing hahaha.

now ... lets tune this huh??? and do it right huh?? ill sit here with my bourbon and you tune that dam car haha

joking.. but seriously.. can only go thru so much $$$ with tuners or else ill just go for a SS Ute and forget it..

[Manuel Kasko]

Hahaha once you get it fixed you will enjoy.

Besides utes are for Bogans

Jez probably won't reply to you now your bringing a shotgun to the meet.

Anyways dude take it and ask a new tuner to have a quick look at your maps and go from there

[AngryRB]

might consider seeing if EFI can give it a couple of runs and tell me if its a crap tune or not, shouldn't cost too much hopefully..

im getting the feeling and by the smell on idle and the big puff of smoke on WOT that maybe its a little too safe and too rich, the throttle is very jumpy too, could this even be related to ignition timing too advanced for cruising???

resembles a car with 10:1 compression or somting..your either engine braking or your taking off ...
