05 GTO lsx 454 throttle ? hey guys just put an lsx 454 in an 05 gto but under 1500 rpms if you try to go full throttle it doesnt want to do anything on hp tuners it showed it would drop massive timing when you would do this and above 1500 rpms its fine any ideas on what i could do to fix this ? thanks for any suggestions
