Before xmas i had my GU ute tuned up by them. The dyno print out
reads before they played with it: 84hp at the wheels and 490nm of
torque. After they played with it 110hp and 660nm of torque. The
problem i have is that before it was tuned i never had a problem
with EGT. Now after they tuned it it gets up too 550deg really quickly
so iam thnking to much fuel. It also chews fuel like it is cheap. And i
have serious doubts that they got 26hp at the wheels because i raced a mates 79 series cruiser ute and stayed with him until we reached the speed limit. Now after they played with it iam still in the same spot when we raced. They wound the boost up from 8psi to 10psi. I already had the 3inch zust with dump pipe no muffler. I took it back to them this morning to get them to make sure it was all alright they told me it was fine.
Any ideas on where to go from here would be much apreciated.
Thanks for you time
