That should be < $600 for brakes (MOST IMPORTANT UPGRADE...CAN'T GO FASTER UNTIL YOU CAN STOP) and around $550 for the JWT ECU and boost jets. That will put you at close to $1200. Now, here you have options. You WILL need an upgraded clutch soon after the ECU upgrade. So I'd save for that...around $400 for the clutch. And if you want to get a lightened flywheel, that will be somewhere in the neighborhood of $400-$500. That will put you at $2000 unless you get your stock flywheel cut...then you don't have to get a lightened flywheel. If you really want, you could upgrade to an aftermarket cat-back, but is sounds like you already have free flow mufflers. That got rid of most of the exhaust restriction from that cat-back already. So I'd recommend spending the $1200 and saving for a clutch...gut your cats if you want (that's free). And maybe get a boost controller if you elect not to do a lightened flywheel or full cat-back exhaust...around $400.
