So my cars been idling like crap since I bought it. It has a t3/t4 turbo, stock internals, straight pipe, and apexi SAFC. I checked the MAF..its fine, tried the ghetto air leak check byt spraying all over the motor while its running and found nothing. Had the SAFC checked by a tuning shop and they said its doing its job.

As of this week, when i throw the car in neutral, or im pulling into a place with a small hill and im not on the throttle, car drops RPMs all the way down and dies. I throw it in neutral coming to a stop light and it dies. Its absolutely killing me on gas...150 miles on a tank if im lucky. WTF do I do!?!?!?!? Im taking it next weekend to get smoke blown up its a** to get a better air leak check.

Dont know how accurate this info is but was told if I took the MAF and rerouted it off the turbo and to its original spot like a normal intake...it should theoretically run like a champ???

Yea i'd look into swapping the maf out completely since you're running a turbo. Grab a z32 tt maf and swap that with the stock one. It sounds like its running too rich and that might fix it. But definatly move the maf farther away from the turbo.. It shouldn't be directly on it.

Not a bad idea. I need to find a z32 maf. May reroute the stock one tomorrow. Thanks for the help man

And there lies the problem.
If you're running a t3/t4 setup, you need an ecu tune, bigger injectors than stock (and if you have 370's they're still too small), a walbro pump, and a Z32 maf.

An SAFC shouldn't be used as a tune, it should be used for more of fine tuning if you will. If you want reliability and safe power you need to look into tuning.

JWT, Enthalpy, and EFISpecialist are all good for rom tunes.

Good luck

ive been building my kat for like 3 years now. ive have every prob u can think of so im pretty sure i could help u. if u want to u can call me and talk it over. im pretty sure i could help u

Besides this...

Sounds like the IACV is dirty or maybe not hooked up?

Hi I have a doubt about the installation of CP pistons to complete the assembly when I realized that the pistons are moving more than usual, the question is if this is normal since the pistons are shorter, the block is in standard and pistons as well.
thanks
