| i want to stack it, but just haven't. you wont LOOSE economy by changing the timing and rail fuel pressure. the reason i think some guys LOOSE MPG is that they found a sports car inside their truck and drive like smoky and the bandit!! but the edge will not hurt your mileage. be sure to get a new chip and not a used or take off, they have updated versions of software, just like computers. the attitude monitor is optional, but adds stage 5 (+150) and is just silly! its so crazy that on the fly you can do what a huge cam and heads do to a gas engine - just by clicking on an up arrow! |
