Best run out of 5 for the day was 13.804, top speed of 99.89mph.
Launches suck.

Got the "transmission overheating warning" once, that's the race I lost to the Tahoe SS.

looks like I'm getting the ultimate racing resonated (or muffled) test pipe for Christmas - can't wait to see the difference then.

I've already got a K&N panel, GST boost pill, UR downpipe, AMS mini battery, and the GST ecu reflash.

Also plan on adding a voltage stabilizer and earthing kit as well as an oil catch can, just for fun and effeciency.

 

With those mods, you should be in low to mid 13s. The exhaust won't make that much difference, but you'll sound great doing it!

Did you use the 'tap-the-gas-pedal' launch method? I'd guess not if you got the slow down warning.
