i have a 97 lt1 firebird when i first bought it, it had about 40,000 on it and it was really fast beating alot of stuff the car was stock now i have 69,000 miles on the car and every body beats me now i added, flows, small stall, shift kit, msd 8.5 mm wires, ac delco platinum plugs , but before i added this stuff it was slow so i added it thinking it would make it faster any ideas

 

Maybe you lost low end torque and it's just your imagination

Or maybe you have a burnt wire or something...any codes??

Unless you have proven dyno #s showing this, I wouldn't be too concerned.
