8 psi of boost in my 2.1 (former) N/A '86 900S

After tweaking brother Mike's (WASSAAB) SPG to 20 psi (more to follow from him, I am sure!), I finally got the LPT dialed in the way I want it...after swapping the '91 Mitsu T-05 in place of the '87 Garrett, I made the wastegate acuator rod as short as possible. The result: 8 psi of steady boost instantly and smoothly. On one slightly uphill pull, in 4th gear, it held at 10 psi. The coolant temp. increased to about 190F after each run to 100 mph, then dropped quickly back to 180F. I am eager to take it to the drag strip, as I am sure I will best the 16.1 runs I made 2 weeks ago. However, I now have significant traction problems in 1st and 2nd gears...before it just chirped second, now it peels second. Need to lower the pressure in the Kumhos! (great tires so far, wet or dry.)
I hope everyone's Saturday weather has kicked @ss like it has in Maryland. Is this really July??
