Hi guys haven't been hear for a while. The problem i have is when the car is ticking over it's fine and revs up to the limiter but under load it wont rev above 3000rpm or pull. It's a gt4 st165 with side feed inlet new turbo , pistons & rings, AFM, No engine codes or light on. Done a comp test and am getting 165 a cross all 4 cylinders . Re checked the timing which is at 10 btc set with the terminals bridged on the diagnostic port. I am stumped . Checked and replaced all vacuum lines.
