Looking for a pressure box that make power in the bottom end & mid. range. Was running Dr. Performance Module 2018 it died....... 1/4 time 0 to 60 1.897 1/8 8.028 1/4 12.47 at 112 mph. Running with 35 " tires isn't helping with 3.73 gears. Need to pick up time from start to the 1/8 mile. I'm running the ppe hot lite programer. Lots of other mods. 2005 dodge 1 ton. Thank for any help, great site new member

Since you have a programmer already, the smarty won't work? But yea the smarty on my truck helped out down low something fierce! But you could always get a TS MP-8. I have no personal experience with them, but its a pressure box you can look into.
