I could not find it on here or your site, but do you have any figures for the HP and TQ increase with your different tunes for the XCALII? thanks in advance.
Speaking from experience--that's a very ambiguous question. Every vehicle responds to a tune differently. Horsepower numbers given for most tuners are "ballpark" numbers anyway. The only way to know how a particular vehicle will respond is to put it on a dyno or take it to the track and actually test it. If you're looking for numbers to compare it to some other product or somebody else's tunes then you're asking an almost impossible question. Matt will fix you up with good tunes and he'll get them to your satisfaction---guaranteed!!
Give Matt at LIPD a call. 1-888-229-0502. I talked with him last week and purchased a SCT XCal2. He told me the best tune on a stock truck is 440 HP and 850 ft/lbs. If you have upgraded head studs and gasket he can go higher.
