Hello,

Can someone point me to the right direction for a tuner in California?
Currently i'm running:
zage turbo TD04HL-15g
evo X 265LPG fuel pump
410cc RDx injector
Ktuner V1.2

im using the ktuner speed density tune, fit is idling fine at 14.7 afr but once i apply load it go too lean reaching 29.4 afr, car start sputtering.

Thanks in advance

 

Good luck with that big dream, you better move states for that to happen. There is no such thing as legal ECU tuning in Cali as of 2021. ECU tuning is now banned across the whole state. So you won't find any legit businesses offering those services any longer. Because the fines for them are very extensive.


California is now also testing modified vehicles for aftermarket ECU tunes. They will not pass you in any smog check, and your registration will get red flagged so you won't be able to register the car for street use any longer. In fact the government is trying to ban most all ECU tunes across the whole US. Google it.
