stacking tunes?

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:

I bought my truck used, it came with a 4" turbo back exhaust already. Althought I can't find any evidence of a tune, I'm assuming the SCT will over-wright any tune that may already be flashed. So it really dosen't matter wheather it already has a tune or not. From what I can tell, there isn't actually a chip being replaced. So when you tune it, your really just flashing over whats already there, effectively erasing a tune that was there previous. Is this a correct assumption?

Ok in a nut shell there is basically two common technologies of pcm+tcm tuning. I'm not a front leading expert on the entire subject and this is only a brief guideline.

You have flash tuning.

This is your best bet and it is accomplished premierely by SCT Flash. Custom files or "canned" tunes extract the oem file or tune and replace it with a tweaked improved file that nets gains in performance. This is the safest and most effective means of building power. At any time the performance file can be extracted and the oem file reloaded under 5 minutes with absolutely no trace or side effects.

Then theres module tuning.

Since I don't play with that sort of play toy childs stuff I can only generalize it's function. Essentially the module fools the pcm with false parameters to increase power. They typically leave a trail but yes if you flash tune your truck it will erase and superceed the previous device. Obviously if say you once had a bullydog programmer, you would've removed that waste of money from the interior confines of your truck and plugged your flashpag tuner into your obdII port to extract and reload your new custom performance file.

Again, just a 2nd grade idea of what a persons options are with aftermarket tuning. Do a search or look back through the archives and you'll find all the factual informative knowledge one would need to decide how to go about tuning.

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.

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.

Listen here!! First off you and a handful of other azzhatz on this forum better learn how to read and not start pulling chit like this! Never once have I made a remark naming or singling out the OP or the person who starts talkin chit or pickin a fight with me. Also, NEVER HAVE I CALLED ANYBODY A DEROGITIVE NAME!!!! Yes I said poser but I'm not the first and I won't be the last when topics like this come up. Also I did not say that you were asking a stupid question. I said another stacking question. DO NOT PUT WORDS IN MY MOUTH! It was never even implied directly at you or that you spent your parents money or what you've done to make your life. SO DON'T PULL CHIT OUT OF CONTEXT OR MAKE FALSE ASSUMPTIONS!!!

Now this is directed to you the OP, this advice will be givin to by all members of this site. If the lame brain at the shop you mentioned offered a try it before you buy it kind of sales pitch in regards to stacked chips,,,,,RUN!!!They shouldn't be trusted with an oil change on a Honda Civic. Since you've been around the hotrod scene a while and you don't mention anything about stacking chips on your 600hp Stang, then what makes you think that perposterous pipe dream applies to a compression ignition engine????
