Hey guys,

As title says, issues with Stage 2 maps.

Mods are:
Greddy Ti-C catback (full 3")
Custom test pipe
stock air filter and intake
Boost pill removed per Cobb instructions

When i run the Stage 2 93 map i overboost to a consistent 27.5psi

When i run the Stage 2 93 low wastegate map i underboost to a consistent 23.2psi

Can anyone shed any light on if the low wastegate map is supposed to underboost? Any reasons why im overboosting on the normal stage 2?

 

do you just hit 27 and then go back down or are you holding 27. 27 psi isn't going to kill your car, i was running it for a while. What are your AFR readings like?

 

I believe the LWG maps are supposed to cut down on boost. I was waiting for the Stage 1 LWG map from Cobb but probably going to get a custom tune before those maps are available for the 2011.

 

27.5 psi peak tapering down. didnt see where it tapered to. i saw the 2.5psi overboost and came straight back to re-flash the car.

 

Uh i believe stage 2 is suppose to peak at 26 psi, so 27 isn't really dangerous.

 

they say stage 2 aims for 25+/-.8. everything else is fine, including knock; so im not concerned now that everything else looks ok.
