Here is a couple vids.
1st vid is a Heads Cam converter 4th gen on a 180shot, the P1x 6th gen, and My Whipple 6th gen. I gave the hit to both cars.
Second run is 4th gen vs my 6th gen hitting at the same time.
Both 6th gens are similar boost. I make like a half pound more peak but quite a bit more under the curve. I am on E40 he is on 93. All 3 cars tuned by me. 4th gen trans doesn't like the Nitrous through the shift. Just posting this for comparison on how much difference giving up the hit makes.
Either way I suggest doing what it takes to continue running E or a blend of because 93 and boost is leaving a lot on the table.

Ok, makes sense. They did ask me what IM,TB,Exhaust etc when ordering so that must be part of the equation.
Nice videos!! Thank you!
