well as the title says im looking for the best tune or tuner for my truck. I have a 97 k1500 4x4 with the 5.7 vortec in it im planning on a 4 inch lift with 33s will hardly ever pull anything besides a boat and im wanting more power out of it. i have never messed with a vortec im a cummins guy but got a good deal on this truck. im planning on dual electric fans and an underdrive pulley kit, maybe a tb spacer and a cai ive been looking at a superchips cortex or the blackbear but i have no idea im new to these vortecs any help please?

I have a '95 w/TBI, and I'm presently running 8° advanced timing. I have no detonation w/ premium fuel.
Out of error, last time I replaced my cap/rotor I set it back to 0° (stock timing), and the thing felt like I had a boat anchor dragging behind it. I learned these engines like a lot of advanced timing.
Your mileage may vary when it comes to how much timing your engine is happy with, I have a TBI riser, chip and headers that come into play also.
Start at 5-6° and advance until you get pinging then back off a degree or two.
P.S. I just remembered your truck will have the OBD II, I'm not sure how this system reacts to timing changes. The computer may try to retard the timing back. Maybe someone will chime in on that.

Just don't get anything from Diablo!
Blackbear tune for sure, way better then any handheld tuner hands down.
