FullFlaps Posted September 18, 2010 Share Posted September 18, 2010 I just bought a 05 LGT. I just hooked up a boost gauge today and I'm peaking at about 13psi. Is this stock boost? If there is stage 1 software loaded onto my car can I flash it with stage 2 with a different accessport? Could I hook the accessport up that I just bought and find out what software is on the car?

gotsflat4love Posted September 19, 2010 Share Posted September 19, 2010 13-14 psi is normal. Did you buy it from a dealer. If you did, you are probably not stage 1. You can't go stage 2 unless you have an aftermarket dp. Link to comment Share on other sites More sharing options...
robbie_R Posted September 19, 2010 Share Posted September 19, 2010 The AP won't tell you anything until you marry it to the ECU and it won't let you marry it to the ECU if there's a pre-existing map already loaded. Link to comment Share on other sites More sharing options...
