I need more HP in my GSLSE!!!
 

What's the most horse power you guys got out of a GSL SE? I have all the racing beat bolt ons ie headers, midpipe, exhaust, and am itching for more power. Is there any way to make more power without going the forced induction route or swithing to a different motor?

Are you looking for bolt on's?

FC intake manifold w/injectors and ECU is worth a bit of horsepower, an Ignition upgrade will also net you a bit..anything past that your gonna have to port the engine or go the way of forced induction. If your really serious a standalone ECU and some good tuning would also help in either case.

Does anyone who has gone this route have any numbers???
