i have a built ls-v turbo and i just changed my t3 to a air research t3t4. my t3 was blown.
well i was wondering when i go to 6 grand it starts to sputter. i dont know why?
is it because of the tune. and cel is on code 10 iat. if the cel is on will it stop from passing 6k? my wastegate spring i think its higher then 10 because my t3 was giving out at like 15psi! this is my first boost setup! so cut me some slack.
thanks for looking.

im running of afc hack and 450 dsm injectors



please keep negative comments to yourself

 

get a real tune

 

you have to tell us how it sputters. Could be that new plugs are needed or your car is simply running too lean from the bigger turbocharger that now pushes a lot more air at the same boost level. Any check engine light for a sensor should be an easy fix and should never be ignored, that can also cause your problem due to ecu not knowing the intake air temperature and cannot compensate the fuel for it.

So first get the CEL fixed, then check your plugs. 90s are over and the AFC hack got to go for a real tune that will make more power and make your motor last.

 

the way the sputters would be like when im boosting and i try to pass 6k it just sputters/flutters and i cant pass 6k.

how can you tell if spark plugs can play a role also?

and yah im gonna get rid of the afc. im trying to save alittle more for a power fc.

im gonna try and get that iat sensor out of the way.

thanks for your help man thanks

 

why a power fc? stick with the oem ecu and just get hondata s300/neptune/ectune or even crome if trying to save money on a stock motor.
You can check the plugs condition and see if the gap is too big also, but that is probably not your problem here, the problem is lean condition.

 

Could be you are running out of fuel, when is the last time you have someone take a look at it. Has it been tuned since swapping turbos? What do the AFR's look like at 6K?

 

it hasnt been looked after i put the turbo on. and when it hits 6k grand it seems that car dont wanna go after..

 

you have an IAT code, you need to clear that first and foremost

you put a replaced the turbo with a bigger one, it pushes more air than the other one causing you to go lean and sputter out.

i would pull the wastegate spring until it's tuned correctly or enjoy your detonated motor

 

yes im trying to get rid of the iat. and what do you mean pull the wastegate spring?
