Have you tuned the FAST? Mine is basic, needs tuning. Cranks OK, but surges at 2K if not accelerating. When first start, have to modulate throttle to keep it going. Once warm, OK. Initially went distributorless, it ran for a while then backfired through injectors destroying starter ring gear .
lost 4 in a month. Helper had added Chevy pulley to crankshaft and faulty crank trigger. Wouldn't go to 50 , so he altered the computer. Could've shot him. Replaced all. Added MSD distributor and locked it out, MSD 6AL for spark, and FAST for timing. Initial 12 degrees, easier start, 20 degrees idle, 34 at WOT. Cranked first time and every time since. Found new FAST tuner and will tune in a couple of days(if money there).

so we can converse. Visitor system is terrible.
On your seat, need one with butt control. Racetech's aren't cheap, but will need something to keep you planted in the seat on turns. Noticed it twice in two GT's
