Recently put a lightly used ssm90 kit on my 01 gt. Got a 2 bar map sensor with a gtp bin file and im running a 3.8 pully with 21 degrees of timing. I only have a 3inch catless dp, Plog, er rockers (from my n/a days) 180tstat, and a stage one zzp tb. I **** you not my buddy put 89 octaine in it by accident the other day without telling me and we were beating on it all day and I never saw more then a blip of kr in hptuners. My wideband died but im running aprox 930mv o2s. Building 6-8 ish psi of boost. Al103s as per zzps instructions (Thinking now these are way to cold because i cant get a nice smooth idle anymore without pulling idle timing and raising rpms to 900+ in hptuners)
So basically what im asking is am I crazy and missing something here or is it definitely time to drop to a smaller pully? The only problems I am having at all are with the brand new trannie shifting like a 15 pound sledgehammer at little to no throttle. And it only happens with the gtp bin file flashed even with identical tables. Otherwise this thing pulls like a mofo. Whips my buddies 3.6 pullied gtp like its not there. Best 1100$ I ever spent (full kit, 60lb injectors, belts, hoses, gaskets, map sensor, injector adaptors, tuning credits, and a new fpr.)
