2000 SS convert 6MT 89k
The initial torque is there but it feels like it falls on its face and doesn't pull very hard at all. I am pretty sure it is stock other than a K&N panel. I am not sure how these LS1 motors are supposed to feel at stock levels but I have to say I am a little disappointed in the performance. I have only had the car for 3 weeks. Any tips on things to check, or if stock LS1s are supposed to feel "sluggish" like this where is the best place to start modding? TB, Lid, Injectors, Exhaust, and Tune? Thanks

 

change fuel filter, check fuel pressure and scan for trouble codes. good first mods would be good cat back exhaust, headers, tune.

 

Put an SLP FloPac on it -- it will wake it up nicely, then look into headers & y-pipe, then tune...

How many miles on the plugs/wires? Clean air filter? Runs a few tanks of good fuel system cleaner, like Lucas.
