its not the gears, when i got my car out of storage it was slow, didnt light the tires up alot, i have 3.08's also. I cleaned my throttle body, maf, and iac and cleaned a bunch of parts, and i adjusted my tps whitch was WAYYYY off. Car was running great, now i can roll out of firsrt, floor it at about 2k rpm and it will just start to light up at 4-5krpm, and chirps second, and when i kinda drop the clutch, it will just SPINNNNN for ever and ever and not move, maybe like said before, your arent getting enough fuel or air? or something like that
