I've got a problem with my 95 stealth tt. It pulls strong threw first gear all the way to 7000 rpms but when I shift to second it pulls strong to about 5000 rpms then just sort of stops pulling. Same with the rest of the gears. I have an intake and a gutted main cat for mods. I always run 93 octane w/octane booster because I thought maybe it was my timing being retarded from spark knock. I also have the factory blow off valve turned backwards to eliminate the goose honk. If you have any ideas let me know.
