Need more power!!!!

[2001silverado]

Hey mike, I put the tune in yesterday and the truck runs fine. Except it isnt making that much more power with the supercharger, I still am using the FMU. How much extra horses do you suppose it would pick up if I install the larger injectors and pump? When I do, does it need to be reprogramed? Thanks Brett

The larger injectors and pump would likely allow for better power everywhere, but how much is tough to say.
Do some homework on some of the forums like LS1tech.com to see what everyone else recommends.

Thanks

Hey I have a 2003 Silverado SS with an airaid intake , a helix throttle plate and a zex nitrous system . I had a lot of transmission slippage prior but seemed to have tuned that out . I was wondering if you had any insight as to what kind of engine tune I could change for better performance also any others . Thanks
