If you read my post above, you'd have read that the closed airbox is the new emissions airbox version for 18/19 trucks, according to Whipple. Not sure why the constant hate on Whipple from you... For the price, it was the perfect option for me. I wasn't looking to push the limits, just a little extra power and more importantly a solid trans tune, which the Whipple delivers perfectly.
I agree not sure why hate on whipple. They have the most R&D on raptor. Worked directly with Ford on this kit. They use the same Dyno Tuner in FLA that ford them self uses.
Shelby and hennessy both use whipple kit. Only kit that is 50 state carb cert.
Are there more tunes that make more HP yes. I want something 100% reliable and not have to worry on CA crappy 91 oct will not have engine damage from a aggressive tune. We all free to choose what products we want on our own truck just be nice not to have negative comments.
All here to share and learn from each others. ok now back to our normal programming lol
