G'day Guys,
Am getting boost spike in 4th gear, usually as i get to 5000rpm. Had the car tuned yesterday after getting a vf34, top mount and pump.
It is fairly consistent too, of about 5 times working thru 4th gear i lost power 4 times. I have read it is common with the 2.5s, but i have a cat in the down pipe and have had it tuned properly.
After the first spike i went back to my tuner and after some mucking around he was certain the problem was fixed but a few hours later i noticed problem wasn't fixed
. My tuner has no idea what it is yet.
Any ideas or any1 else had the same issue with the 06-07?
cheers
