could you stack the ppe on the banks raise the rev limiter, have the change on the fly, lots of power. i believe in the banks i have a buddy with a lbz it works great looks good and has had nothing but good luck, with it, not a big fan of the ppe i had a lly with a pred, and a friend with a lbz with a ppe and it did have near the sack mine did. but i want to shut the regen off and cut the exhaust off mine and get some real **** on it. so i can get better than 15.6 mpg. its getting old really fast power is one thing ****ty millage is another along with 4.00 dollar fuel. the government needs to stay out of **** they dont know anything about.
