[QUOTE="gtmustang00, post: 16240176, member: 12896"] Lund tuned the motor originally....car was smoking on decel. Dropped back off, took motor out. Engine shop said motor blew a headgasket. Fixed it and upgraded rods/pistons while in there. Said to put 1000 miles on it before putting on dyno and going WOT. Finally put on dyno and here we are. I don't seem to confident in Lund at this point. Motor was originally a brand new crate motor with 0 miles. [/QUOTE]
