Ill put it to you this way, Don at Modular Madness, has made 700 HP, with just a basic file Diablo chip and Mafterburner in his KB powered cobra.....I have made reasonable HP but massive torque with it due to the limits of my stock eaton....The cost is around 300 bucks and its a 3 wire install, Ill send you a pic later....once installed (15 min later), your truck will run the same with all values at 0. If you run your truck and you hear detonation on top, go into the mafterburner and add 10% fuel at the rpms were you felt it..The software is just a graph of a RPM scale and arrows going up and down that allow you to increase or decrease fuel....But remember, any mods you do from that point on will not require you to keep redoing you chip anymore, unless you want to change your timing .....

 

so how long have you had it, where do you splice into the wires at. will it work if it want to richen up/lean the entire rpm range?

 

I have had this for about 3 months now, after I seen a 16# KB powered Harley use one and make 450 rear wheel and 580 tq...You splice into the wires at the ecm harness behind your battery, these just take quick crimp connectors. Yes, you can use it to richen up your whole rpm range like I do...And if you put bigger injectors like Im doing, you can adjust for that too..the rpm range goes up to 7 or 8000...after my shift points are met I just set the rest of the values to 10%.

 

who did you buy it from? how much if you can disclose?
