So I just got my car back from SG. I upgraded the plenum, throttle body, wastegate, and ECU.

I noticed that in all gears besides 4th, the boost will go up to 1.3 and then hold at 1.1. In 4th gear though, the boost will go up to 0.8 and then hold at 0.6. I tested out the boost in each gear several times and it does the same thing in 4th gear.

Anyone know what might be happening?

Thanks!

 

Well, I test drove it a few times tonight and it's back to normal. Don't know why it was doing that in the first place.

 

yes I know.... ur in limp mode... and or the throttle body is shutting down cause ur hitting 1.3 bars... I had SG stage 5 set up... I know all about it...
get the car back to them... if ur running hybrid turbos.... get them to dial in the wastegates correctly... or if ur really sneaky, get Dan to install a Throttle body bypass.. they know what it is...
but u cant run 1.3 bars on 91 octane... and get them to install a 5 bar fuel pressure regulator... ull need it at those levels....
