I just had LMR in Houston dyno tune my 2010 2SS 6 speed manual. I am extremely pleased with how the car has come alive. So much more fun to drive at lower rpms (2-3k). The car always felt held back until now. Now the car is always breaking loose.
Conditions 43.3 F, 29.9 Hg pressure, and 59% humidity.
The attached image is the "STD" graph with the final pull after dyno tuning. The car has only had the following: Cold Air Inductions intake, and Pfadt long tube headers with cats, and muffler delete. Results: 432 HP and 432 ft-lbs.
