4.8 L/lr4/engine mods

[kerrige]

I have an 01' GMC sierra with a LR4 motor, full exhaust-k&n FIPK-superchip, looking for some engine mods maybe a better cam, still kind of new to these vortec motors it looks very complicating uunder there. any suggestions?

Custom tune. Nelson is a very popular choice. Gears and Posi are a good investment but common recommendation would be a trutrac with 3.73 or all the way up to 4.10 After that bang for your buck Ebay has some nice headers for very little $ add a magnaflow straight thru 3'' and losing the cats is a good idea. After that a 3k stall from Circle D. You should be moving after that.

Edit: just noticed you already have an exhaust my bad.
