New 306 with about 1.2 miles on it and 8 hours of trying to get it to run right, It has The trickflow H.C.I. along with cold air, 24 lb. injectors underdrive pulleys, catless exhayst bbk headers, and new a 75 mm MAF, I also upgraded throttle body and egr to 75mm. My problem is quiter simple I don't know what the fu*& I am doing apparently, I have done lots of carbed, non computer enginnes, and thought I was cool, this car is owning me, I got it to idle on its own, made it around the block and had some bad ignition knock, advance it and it wont turn over, retard it a little and it backfires, anyone want to buty this from me? just kidding. But I am lost, i have heard alot of guys on htis site stress a tune, some say dont believe it you dont need one, at this point I am out of budget and cant afford the burnt computer from summitt, any advice of what to try ? the only things not new are distributor, wires, timing cover and oil pan, WTF?
