First of, Im not a poser asking a stupid question, if you think its a stupid question then you aparently know the answer so its " stupid" to you, Secondly, Im not spending my parents money, Im 27 yrs old, and been on my own in the army since I was 17 yrs old, and make my own way thank you. So instead of your brain dead reply's, answer with respect, or dont reply to my posts because you just sound like a uneducated half wit.Effing Christ on a cracker!! Another poser asking a stacking question? Not sure if it's any worse than obsidians air filter revalation. I am a man of common sense and stacking chips is obviously not going to work. Same principle that by adding an exhaust, air filter, tuner of any sort under the rainbow and low drag coefficient motion lotion that all have claims of increased fuel mileage in factors of mpgs doesn't mean you're gonna take a 15 mpg truck add up all the 1 mpg here and 5-6 mpg there across your entire parts list and wind up getting 23 mpgs!!! So if the objective you people are trying to achieve by stacking is based off the mentality of this tuner claiming 150hp and this one 105, your not going to make 255hp over the baseline manufacture numbers. WTF!?!?!? Spend your parents money on real engine parts that lay down the big numbers for real. But that involves doing your homework and getting dirty tearing down your engine which means your won't be able to meet at starbucks on Saturday night to organize a race. :doh:
Now, I asked this question because the place I got my 4 inch turbo back MBRP exhaust and my tune installed had recommended that, and or injectors and head studs. They also offered for me to try it before I bought it. ( stacking the tunes ). I wanted to know if this was plausable, and or safe with the studs and injector combo. Im new to the diesel scene, but not the hot rod scene as I have had multiple cars, and my current is a 2011 5.0 GT stang with over 600 RWHP. Im just getting into the diesel performance, if anybody else feels like acting like a tool, refrain from replying to my question. If not, I apreciate all POSITIVE and HELPFUL feedback, thanks.
