But your gonna laugh in the face of the 4.3 power when you ride in a boosted application or a NA starting with the 5.3
Wow! 20/21 is incredible. I'm averaging 17 mixed hwy/city now. Would you recommend pulling out ALL torque management a high mileage truck? Mine is a 2001 with 124,xxx miles. I know what you mean about the power difference. A co-worker has a Radix'd 02 Z71, and I love how it pulls. That's my plan for my '86. 5.3 with a Radix (income tax check).
Thanks for the help Ducky!
