well i went to the track last friday and ran the GN 4 runs best for the night was 12.98@102.6 with a 1.7 60ft. not the fastest but know i know how it feels too launch @9lbs of boost and almost snapping your neck backwards. pretty cool feeling. i also ran a z28 camaro 96-98 nice too with a 100 shot of NOS had him the whole way beat his 13.3 to my 13.1 not to shabby for a 141xxx mile gn with homade tunning and no scan master of anykind but i was consistent with 13.0's for 2 runs looking for a guy here in vegas or in cal to freshen her up like new bearings and pistons ring's n stuff might even girdle her how much would this cost me i want to stay stock for know like the basic stuff i mention and does any body know some one here on the west coast?????thanx guys later.
