anyone do this its a lot different wish I could have done a pre-post dyno runs but my impressions are wow! Its not what I expected. this seemed to do more for torque than HP. Right off idle it just goes. the trans shifts alot smoother. The large BLACK Lingering cloud at hard take-offs are smaller but has a longer more noticeable smoke through the gears. Smarty #5 25psi boost and under 900 degrees untill lock-up shifts and 1300 untill you back off. Rail psi has become so much more steady with no increase in psi over program. One thing odd the fass pump fuel psi is up about 2 lbs. Now for some news you can use, the fuel mileage numbers. We all know that this is not an exact science, but I use my truck as a route truck. (using the same roads each week). I am seeing a increase of approx. 1 mpg. This is in a 20 to 25 mph winds that we have had here in California this last week. in case your wondering $4. 39 per gallon
