First Log on my stock 2007 Spec B...max boost 11.xx?

Did you take the intercooler off by any chance? I would look for any disconnected vacuum lines around that or the wastegate/actuator.

 

 

No. I haven't done anything to the car except install the Kartboy STS. Since the car came with a COBB turbo-back, I'll start at the turbo to DP connection and go from there. Car is slow as molasses...:lol:

wow, that's gotta hurt, I'm sorry to hear that

 

with my 05 GT, I was getting around 12, 12-1/2, max, with the stock map. Not sure what the "difference" would be, stock to stock, but in my (*still-learning*) opinion, the rest of the log looks pretty normal.

The best thing to do is to try troubleshooting yourself to help eliminate possibilities. Take off your intercooler, make sure your lines are all secured. If you had a leak (pre turbo") you would probably hear it or notice a difference. Check your throttle body to IC connection.

Agreed. I just wanted someone to chime in and tell me what the max boost is on the car in sport # mode or where I can find the info. I want to get an answer before I start taking things apart.

Logged again. Zero wastegate duty cycles. Anyone have an idea? Did someone upload a map and zero them out so they wouldn't overboost on the COBB turbo back exhaust? Thats the only power mod done to the car. Map seems very conservative.

 

Here's the log from today:
