SPG Modification Issues Resolved (long-ish)

Issue 1: Does changing the size of the restriction inside of the BPC solenoid do ANYTHING: Hell yes. Huge difference. RUN out and do it NOW if you have not already. Proven to me by doing only this mod on a car, with little else done to the engine.
Issue 2: Wheel arch rubbing with 16" wheels and 50 profile tires: Bought spacers for above the bump stops for a 91 900 covertable. NO more rubbing. $20 fix. Word.
Issue 3: When tweaking your car, you MUST accomodate for the added fuel needs of the car. Tweaked a car today without adding a higher flow FPR (my car has 3.0 FPR and 30 lb/hr injectors) and the difference was obvious to me. Don't forget about turning up the overboost cutout switch (windshield faceplant switch), too.
Issue 4: Clutch slip under heavy boost: Installed a new pressure plate and new clutch disk (stock units). No more slipping, at all.
After many trials and tribulations, my SPG is where she should be: 18 PSI and holding. No turbo bounce, no nuthin. Got up over 130 mph today and did not even notice I was going that fast, since I started from about 55 mph, floored it (kept it in fifth), and about 6 seconds later I was at 130 (WOT, @5200 RPM). Dang. Lovin it. I owe a lot of this happiness to this board... this wonderful forum for ideas and suggestions. Experience and experimentation. ROCK ON!!!!
