Modifying someone else's tune I bought my car with the blower and already tuned. I'm currently only making about 3 psi of boost due to a fubar FMIC. I'll need to replace that, but in the mean time I've been trying to learn as much as I can about tuning. It should be around 9 psi when that's done. I like to play around with the software and research, I just don't actually upload it unless it's something very simple (like the speed-o correction). 
I recently learned when it was in the shop for a post-purchase audit that it had 25 degrees of advance at peak torque. The tuner was appalled and took it out before going any further with it. Once they discovered it had an intercooler problem we didn't get any further at all.
Here's the table now and I'm tending to think there's still too much advance for my setup on pump gas, but that's just based on what I've read to date.
Thoughts?
