Meister: Thanks man... It was the first time out since adding the GSM Mod, and MagnaFlows.
The GSM Mod helped cool the car down faster, and kept it at about 203 degrees on the Engine temp (Diag. Screen, not oil temp in the main screens).
The torgue mod helped, but on several runs, I was burning rubber off the line instead of hooking right up. I did NOT run with ESP on.
I take it you're powering the GSM fan switch off of fuse slot 9 now. Good show.
'Looks like it's time you added a 180 degree thermostat, XCITsNU. 203 degrees is the temp of the stock tstat, at least on the 5.7L. The thermostat is fighting the fan. Drop in a 180 and you'll be able to cool her off to 180 or thereabouts. And the 180 thermostat will be just fine all Winter even up in your neck of the woods. 'Ran a 180 all 3 years I was in Alaska some time ago, with no problems of any kind, in a modified small block Chevy engine.
Suggestion: Next time try leaving ESP engaged (no skid icon showing) and see if your launch improves. I didn't think of trying that either, and even with my 5.7 I was burning wildly through first, and half way through second, with both the ESP off and the tm switch engaged. I've wished, in hindsight, that I had thought to try a run with the factory ESP OFF switch in the normal position to see if that helped hook up better.
