Over boost fg xr6 turbo

Hi all,

Just recently got a flash tuner, and I'm having an over boost issue. Mods are hdi fmic, k&n panel air filter, 4" s/s xforce turbo back exhaust system, 72lbs injectors and my turbo is factory stock . What's happening is, when I'm in 6th gear with about half to 7/10 throttle I am seeing 18-20psi on my boost gauge @ about 3000-4000rpm (I don't try to push it once I see the boost gauge go of the scale). I thought the stock turbo couldn't push much past 15psi? Another thing is, it doesn't seem to be running bad in anyway....if I didn't install a boost gauge I would be none the wiser.

Thanks

You need a better actuator.

Who tuned it?

Yeah stock turbos max out at 15oddpsi, but that's low load full revs, when your down low it could go to 25+psi then taper off to 15psi once the load dies off.

Has there been many problems with mail order tunes? It's not detonating...

Get it tuned mate.

Mail order tunes with your mods are no good imo.
