@SteveWK: You always have to be cautious when adding power to these cars. Nothing is bullet proof but you can take precautions. 1. Use a tuner that is well known for working on THESE cars. If I had it to do over again, I would have it tuned by Lund or someone like him. 2. Always check your oil. My car was eating oil and I didn't watch levels as I should have. I went down several quarts of oil fast. I think a major reason for the fail was because Oil pressure was way too low and I wasn't watching the helm close enough. My car was gobbling oil up quick. I JUST got an oil change and they put in an extra quart at service. When I checked post fail I was down several quarts...not good. Keep an eye on your ride. 3. For weeks I felt that something was wrong with my car. It was losing power higher in the power band like it was fuel starved or the mixture wasn't right, I still have to check by BAP to make sure that didn't give up the ghost as that would also help explain things (not enough fuel BOOM). I would have put in a new and better fuel system in lieu of BAP if I had it to do over again. Anything that can compromise fuel delivery and cause BOOM- not good. 4. If your car doesn't "feel quite right" dont drive it, and at the very least don't race it!!! Duh. I raced a guy when I knew my car wasn't 100%. Don't let ego bankrupt you and make you feel stupid. 5. Don't add gobs of power with bolt ons ALL AT ONCE. Make small changes and see how your car responds. You never know what YOUR engine can take until too late. There will be variations in compression between cylinders and that is normal (So I"m told) but when you start to see that variation GROW and the gap get wider between your passenger side and driver side, STOP and ASSESS. I had a 10% variation exactly between my 3 driver side cylinders and that grew over time. I should have stopped and had the engine broken down to assess (expensive but not as expensive as now). In a perfect world, build your engine to properly handle power. When I rebuild I will SLEEVE the block out of an abundance of caution. I will build the engine to take higher RPMs and reset the rev limiter higher and NOT HIT THE REV LIMITER with any regularity (not possible to never do this but do best to avoid). I'm not one of the more tech savvy guys on the forum with extensive mechanical prowess but I've learned through the school of hard knocks. Good luck to you Steve!
