It has defienitly raised in temp since the tune was done. 430kw on a stock motor is really leaning on it, isn't it? Is 12.8 too lean in my application?

djqc Member 291 Member For: 13y 7m 14d Posted 03/02/13 11:33 AM Author Share Posted 03/02/13 11:33 AM My original query with the car was the higher engine temp.This is my worry.

Meant to say lean not low. Car does feel good but does run slightly hotter on the temp gauge than pump fuel.

HYPEDF6 Donating Members 301 Member For: 12y 5m 13d Gender: Male Posted 03/02/13 12:54 PM Share Posted 03/02/13 12:54 PM Isn't this a XFT or MT tuned car ? Either of them have done enough to know what the go is. I would put enough trust in them to not worry about it mate.If it was another workshop in WA then maybe I would sh*t my pants a bit.
