I can honestly say I felt F-All difference after having the 3.9's fitted except for earlier gear changes, tailshaft problems etc. There was no Holy crap increase in acceleration.:(
Whats everyones thoughts now. The chip looks like it has taken a minimal 2 10ths off but the 3.9s have left the 60ft basicly the same. It should of given it a huge wake up i would of thought

used:
Where should I direct my attention to fix this problem in my ute that clearly seems to be there???
