2015 Denali 6.2 4x4 a8. I currently have afe stage 2 intake, lt1 manifold, 1 7/8 long tubes, 3.5" catback and tune. Any performance bolt ons I'm missing besides e85 conversion?

underdrive pulley?

Anyone have any kind of numbers on the pulley? Also has anyone tried out the Holley high rise intake.

A high rise intake would be a waste of money unless you were going to turbo the motor.

That's what I figured but had to ask. I feel like the lt1 manifold was a waste but still need to get the tune dialed in.

people with square port heads over on tech are making great gains with vic jr manifolds. it would require an accufab style throttle body and a cam cut that's geared towards a single plane intake. nitrous distribution is better on single plane if you ever go that route in the future. I had a vic jr on a LS2 and the throttle response was insane compared to any efi style intake I've run in the past. not sure if I should attribute it to the intake, or the carburetor though. maybe a combination of the two. the best news is it's cheaper than any crappy *** FAST intake.
