From idle to wot it goes to a full rich condition. If you hold the rpms bout 1500 or higher it will rev without going full rich. Did figure out that every once in a while the egr motor gets stuck causing the ide to be crappy. Tech 2 showed the egr code. Could my exhaust have too much backpressure? I found zero exhaust leaks. My friend with the tech 2 scanner is helping me but all hes done is oem chevy stuff the performance upgrades is new to him. He is going to give me the recorded info from his tech 2 so as soon as i get it ill post it up.The scanner showed no codes while these events happened. Any thoughts would be appreciated. http://www.compcams.com/Cam_Specs/Ca....aspx?csid=590 When i bought all the engine parts from comp they told me to purchase the fast programmer. Iv had nothing but problems getting any support from them.

Discovered the upper intake is warped. Removed the upper and lower intake to be resurfaced. Almost thought i had a burnt valve or a bad lobe. Cylinder press is between 100 to 115 lbs. Did a visual inspection of the camlobes and they all look perfect. Hope this fixes my problem..
