TVS Dyno
Just finished dynoing a guys 07 Cobalt SS TVS with a 2.9 pulley that I tuned today.
Car runs on pump gas + meth.
His mods are OTTP intake, OTTP heat exchanger, dual pass, vibrant header and downpipe, 2.5" catback, CF clutch and DSS axles (doubt those affect the power at all).
330/284, not too shaby considering its only at 20 degrees and 11.5 afr.
Didn't want to tune it for any more power since its his DD.

I have a set of 80lb injectors, a TVS and a 2.7 pulley waiting for me to find time to try and tune the 80s for my car 
E85 isn't an option in our area, so we have to setttle for methanol injection. There is a race gas shop around here that sells pure meth for a little less then you pay for premium gas at the pump.

Nice,i'm going back to the dyno hopefully in a week,i put the man pulley on and did some more tuning,she pulls hard all the way through the power bandIf i can squeeze at least 15whp more than the numbers in my sig,i'll be happy.

i will say this.... don't expect your car to have those #s in the summer! I was puttin down 343whp in 60deg weather, now that its 30 deg and below, there is a huge very very noticible difference in power! the colder the air the faster you go! so in the summer expect your car to be slower than it is now! if i were to go dyno my car now i should probably be puttin down well into the 350#'s maybe even the 360#! I LOVE THE COLD WEATHER!

I probably won't go back to the dyno until the E85 Summer blend is back. Which will be about May 16th.
