This is my R33 GTST

i was having the same simptoms as what you are explaining, try different injectors first and see how it goes.

Da Boss, please put your stock or any other injectors in and change those yellow foolishness. I told you they are no good. Trust me on that. Once you do that you will be fine. Sparta!

I got my ecu remapped by toshi and the results are amazing. Thanks Toshi.

ok thks I answered you.

Currently I am on 10 lbs of boost and my Wideband is reading 10's by the time I hit 4 lbs of boost. I am running 40 psi on my nismo fuel regulator and my AFC is zeroed out.

Ok thanks I will do that

I have a AEM Wideband and afc neo

My thing is there is no one here in the bahamas that does good tuning, as a matter of fact we don't even have a dyno here. That is why I wanted an ecu tuned for my mods and from the threads i have read Toshi is the man. So I want him to tune my ecu.

Do you think this can happen?

Toshi what about me any help for me I don't want an aftermarket ecu!

Yeah I did that and sometimes it helps and other times it still does the same thing.

Since i installed my 550cc injectors my rb25 stumbles only on inital start up. After I start it up once and cut it off and start it again it starts fine. This only happens when the car cools down completely. Any Ideas why this happen?
