Just got on the board and wanted to introduce myself. I have a 99 Chevy Silverado Ext-cab and just have basic bolt-ons. I just ordered a Nelson Performance Tune and can't wait to get it. How many of you have had a problem with that VSC, with the e-fans?? I am looking to doing an LS1/T56 swap in a 76' Chevy C-20, either the T56 or a TH-400 with a gear vendors overdrive. Let me know what you think. By the way my name is Pete.
