Hey guys - a friend of mine with a 2003 RCSB and a 4.8L wants to get some more power from his rig....is there anyone who lives in the Tacoma/Greater Puget Sound area who has HPT for 2003 Silverados? I'm sure he would appreciate any help.

 

Sorry but I don't know anyone with it . I just ordered HP Tuner for my 2004 GTO and 2004 H2. The people I know that have it all have F-body applications.

I have HPTuners for that truck, but I'm in Mount Vernon, about 70 - 100 miles north of him. I am also not an expert and wouldn't know what to change except to remove torque management. But if he knows what he wants changed and is willing to make the trip, I could help him out. (Can't go down there, as I'm still recovering from flu/pneumonia that had me off work for a month).
