ECU does make a lot of difference ey, hmmm vteckiller, wif fuel pump in regards to mah car, after dyno, i had to retune n minus mah fuel setting as 2 rich, prob coz mah auto ECU for GSR, but den does changing fuel pump n having fuel regulator increase some hp wif SAFC from my previous dyno tuning? coz previously all internals were stock, n not much mod, but had evo1 turbo got onli 210++ at wheels lar, i kinda think still under performing... if u say wif ECU den i reckon will do get more HP, but wif fuel pump, injectors n regulator, does it realli help to increase a lil more n utilised da turbo more?
