Why.....


  1. Zero to 60
  2. Cruise at 80 (While comfortably listening to tunes)
  3. Little Heat Transfer
  4. Tire Spinning Torque
  5. 2 Year Factory Warranty
  6. 17 + MPG


After driving an LS truck its hard to drive my 300 TDI.

I am definitely not a fan of the Lokar shift, but I think it has its place. On a budget build they are probably the cleanest cheapest option.
 
Well when I cruise on the interstate it drives well. But I'm getting terrible mpg. Around 9-11 mpg. My engine is the LS 376/525 with the ASA cam shaft. I also have a 110. Is yours a 90 or 110 and is it the stock LS3 with 430 hp? Did u tune it after install?

Def a 110 you can see second row hinge in one pic.

Probably the 430 HP. Your mileage will suffer with that cam, especially without a factory or any special tuning. It also loses low end torque.

Swap in a stock camshaft. That ASA (while no one is willing to provide specs for it or the ASA tune) is a race configured profile. It was never intended for street use. I'm sure you're fueling/timing for your application is far off. I've got a GM streetrod ecu and harness for my IIA/90 LS1 project (started over 10 years ago before anyone else ever considered a LSx swap).
