never heard of that b4?

the standard ecu senses the boost being too high and it cuts the fuel delivery. it feels like it cough and splutters at a limiter at like 4000rpm just as its about to hit boost!

i had to get a horsham chip in my 200sx to eliminate it. it was only after id put on the fmic that the turbo was boosting a little higher and causing it!


does it feel like ur foots boucing on the acceletor and the cars all jumpy?

[jdmjimmy]

its not rev limiting anyway jus gets very spluttery standard fmic
