Can any body on here recommend a tuner that can map a apexi power fc on an early version 3 sti . Aparently a different lead is needed for the early pfc
and no one seems to have one. Any help will be great.

Had mine done at Zen (v3 STI)

 

how the difference when before and after the pfc was install on your v3?

 

had mine supplied and fitted by zen performance, lets put it this way im running 1.4 bar boost on a engine that has done 84k miles and its never been rebuilt, and the car pulls like a rocket, its much better on fuel now and alot smoother than before, best of all the midrange acceleration is fantastic

 

Depending on where you're located

Mocom Racing - Essex/London
JGM Kent/South
Zen - Midlands
Andy Forrest - Scotland/North England

 

Even as standard my car was quick, and what I'd call a 'punchy' delivery of power.

i had a FMIC, decat, induction. If you're pootling along and want instant acceleration, then a down shift is required, but there is really no extra noticeable lag. Better on fuel consumption too.

Now it has a better spread of power and you're on the wrong side of the law very quickly, pulls all the way with seemingly no end. The estimated figures (Power/torque around 300) would portray a modest increase. However, on track nailing it side by side with a 450bhp type RA, the RA only crept past down the straights, not blasting past me as I and the other driver expected.

So I guess thats what people mean by 'don't chase figures', and drivebility is more important.
