My car is just about ready to be tuned. At this point, I'm just hunting for what is presumably a vacuum leak (bouncy idle, low vacuum Hg). I'll be needing a tuner who is familiar with Water Injection on a rotary. I'll be injecting 315cc p/m on an AEM W/I kit. Ideally, I need someone who could tune up (marginally), with respect to EGT target ranges - I'll be running dual loggable pre-turbo EGT sensors. Further, as far as my understanding on W/I (which is limited), it seems that with water inj. specifically, AFR's need to be tuned more lean than usual.

Can someone point me to a tuner who is knowledgeable in this area of tuning and could set me up nicely? Again, for an Apexi PFC, THANKS!

 

What part of CA? Nelson at RRR in Santa Ana tuned my PFC as well as my AEM Water/Meth kit.

 

nelson is good, but hes way to conservative. depending what you are looking for. but from experience i think neptune speed did a better tune overall when i had my PFC. but with my AEM EMS i stick with nelson.

 

Hit up Mazpower (Glenn) on the forum. Www.illicitperformance.com

Made 335 rwhp on my fd, stock twins, meth injection, 12 psi, using PFC. Got 50k miles out of the motor with hard driving.

 

i have had my car tuned by both yoshiya neptune speed and nelson at rrr. They are both good tunes although i would recommend nelson cause he puts extra attention to detail and makes the car just feel crisp.
