You do not need to get us the shifting rpms on your CPW's in order for us to tune the truck - perhaps you misunderstood how we phrased something on the CPW's, I'm thinking? At any rate, you don't need to do any of that until AFTER you get your tuning - meaning while doing the datalogging to double-check the tune.

In stock trim, you will hit the top sped limiter long before you hit the full-throttle 3-4 upshift point - and yes, that is what I am talking about, is either a WOT upshift into, or a WOT downshift out of, 4th gear (Overdrive) - that is hard on any 4-speed automatic overdrive tranny, and thus our recommendation to avoid doing that - which you will see explained in detail on your docs when your XCal 2 arrives.

And of course, once you get your tuning and the top speed limiter *is* removed, a 3-4 WOT upshift will occur at about 110-120 mph anyway, so you really don't want to be doing that on public roads, as that's a trip to jail in many cases if you get caught, to say nothing of the danger factor - which is even worse if a truck does not have the necessary suspension & tire mods to travel at triple-digit speeds safely just from a handling & control capability standpoint!
