I knew there would be someone who had to have an issue with what I said.
It's funny how I know for a fact that the acceleration improved because I actually drive the truck every day, but someone always knows otherwise. Every truck is different.
I had a sluggish response and poor acceleration before installing, and afterwards I noticed a clear increase. Sure, if you say you can't increase either horsepower or acceleration separately, then their must have been an un-noticeable gain of horsepower not worth mentioning.
Sorry about that.
