I have cat back Roush dual exhuast dumping in front of the passenger rear tire, cold air intake, throttle body spacer and I have programmed the computer to modify rev limits, shift points and the speed limit limiter. The tail pipes are pitch black. I think I am dumping fuel. When I punch it around 70 mph she backfires before taking off. Do i need an exhaust balancer? Or is the problem something else?

Thanks

 

you must have forgotten the muffler bearings

 

I think he forgot the halogen bulb fluid refill and he didn't mention the viagra additive to keep the transmission firm he needs to get 'em done asap







seriously it sounds to me like the tune is way off, is it a canned tuner or did you get a reputable tuner to tune/email you a tune for your truck and your mods? if you're running a custom tune put the stock intake back on before you do some damage (if it's not too late)


also take that awful waste of metal (the TB spacer) and put on your desk so it can the most expensive paperweight you ever bought
and it can function to it's full potential

 

x2!
what motor are we dealing with here? mileage? ever been tuned up? and yea we need to know what kind of tuner you got here.

 

Have you checked your Flux Capacitor?
