I'm here looking to learn. I have a 97 SS S10 that I have a Mach performance procharger kit to install but I want to learn to tune a little before I install it. I do plan on doing the 411 pcm swap and use hpTuners but at the moment I have the JET DST tuning so don't ban me right yet. I do have a wideband installed and it has a lean stumble right off idle im trying to correct right now. Ill search the site for info but any help you can give I would appericate!
