I have a 98 12 valve 5 spd 3. 54 reg. cab that I have moved the stock plate forward and rack screw 1 turn in and added 4 inch exhaust. Every thing else is stock I love the way the truck runs. Timeing is at 16* I forgot about that. The problem is the egts are 14to1500* under load. Boost is 30+ psi Whats next?
