I'm looking for about 420-430 HP at the wheel...

Coastal huh?..... I'll look into them...

Pulley, i've ben told to do a 5-6LB lower
Exhaust, i've been told Bassani for sound/performance
Intake, I've been told to go a modified 01+ intake system
Chip, I've been told to go with a Diablochip
Lowering kit, 3/5 drop .... from who?
anything else?.. any other suggestions??
