Forgot to mention to you guys that are fairly new to this board.. I've been boosting 10-14 psi on stock internals for just barely over a year before I had to upgrade my bottom end. I had the proper tuning on my stage II with 450cc (not 440cc) custom made injectors along with the MSD-DIS2 boost retard option. I had the old style AFC at first and that was doing the a/f tuning and ALL the tuning was done ON THE DYNO with fine adjustments made to my AEM cam gears. This is a year on stock internals ladies and gentlmen and I'm sure all the old timers on this board remember that. This was done BEFORE I started abusing the holy fuck out of my car with race after race after race. Sometimes I keep quiet on this board because I like to read the testimony of people that thrive on the ignorance of others for praise in false knowledge. But lately it's been getting to me.. so I'm not gonna keep my mouth shut anymore.
