this is possible, but even if i lay off the gas it only goes up maybe 1 mpg.
bahh maybe ill change the plugs and wires? also i owned an srt-4 before my truck and the thing to get on that was the msd (sp?) wires, is it the same for silverados? and plugs, if heard its just a bunch of hype with the different stuff you can get. Any opinion on that?
factory wires are great. Stock plugs usually last 100k+ without issues. Is your convertor locking?

when you ask if its locking, do you mean is the tranny slipping? or does it try to take off with the brake on? If yes, then no to either. It does shift pretty stiff though, it did that even when it was stock.
was wondering if it locked the convertor at cruise speeds. Usually the convertor is unlocked except in OD, meaning the engine speeds change easily if you give it a little more gas while the MPH doesn't change much.
