Purchased a Kat Matrix G-Force Meter last month to chart progress on upgrades to our 2009 GM. I know its not official drag strip results, but it is repeatable.
These are 0-60 times run 6 times back to back
Baseline - 9.00
K&N Panel, ADDCO front & rear bars - 8.85
Hypertech E-Con Programmer arrived today. (BTW free upgrade to the top model this month via internet. Installed program tonight.)
First run 0-60
I had traction control off and applied some throttle against brake - 8.55
Traction control off just flooring - 8.45
Traction control on, some throttle against brake again - 8.25
Traction control on, less throttle against brake - 8.00
Traction control on, just flooring it - 7.45
Same as above - 7.00
A Seventh run after a cool down, same technique as 5 & 6 - 7.25 What fun!
That is quite an improvement over stock tune. Quite the flat spot still @2500 - 3800 rpm. Maybe ported upper manifold (ADTR) will cure that, along with the duals next month. Seeing the needle bounce off redline with nice firm shift is great stuff. Intake sound (without the snorkle choking it) has a nice snarl all of a sudden.
More next month.
