my bf's old gt ran 1.2 bar on a td04 on a fuel reg, 330's and safc, done it, nailed it for 8k miles until went forged... yes i know emanage is the best way or unichip, but for the money and pure fact a bottom end is £200, the hell with it...plus my bf wanted to prove a point lol
only cost him £300 for it setup and parts too, 239bhp and 223ftlbs at 1.15 bar, safc £80, injectors £30, jam bcc £40(greddy you can buy new for £60 and go into map sensor)fse fpr with gauge £45... setup on rr £100
the good thing about mapping though is the fact it'll be better on fuel, the fueling will be spot on, and you can squeeze a wee bit more of a figure out of it, but what does that matter, back in my dads day twin 40's and metering units ruled the world :haha:
