I still have my TT pump gas chip in the car but I just got the Alky chip in the mail. The car runs OK with pump gas chip, is it bad to run it with Alky? Will it run rich?
I am going to put in the Alky chip I just wanted to set the boost where I want it before I put in the Alky chip. What is the difference between the two besides more timing?

The alky chip sets the boost solenoid duty cycle much higher, so if you're still using the solenoid, the boost will go way up (compared to the street chip). So be careful. Otherwise, mainly timing changes. You can run alky with the street chip if you want.

Thanks guys, I drove it around with the Alky chip and it runs well. All my SM #'s look good. I got the boost up to 20-21 with O2's at 769 0 KR.
