Just wanted say hello and great site! Finally decide to take the plunge and start tuning my truck and what I have read here has really helped. So, big thank you to all contributors.
I have a 1994 K2500 (6-lug) 5.7/NV4500, 3.73 rear, headers, Flowmaster y-pipe, no cat, Flowmaster 40 series muffler - 3" single in dual 2 1/2" out, ultimate TBI mods w/VAPR, MSD 6AL, underdrive crank pulley, K&N filter, four wire O2 sensor, and now a custom tune. The engine is all stock other than these mods. Thinking of doing the ECM to PCM upgrade soon, going to install a '7427 PCM.
My goal is to help improve mileage and try to get some more punch for towing.
