Refer me to a "real runer" who will do the job for less than $150 in Cantral Florida, and you're on. This is my daily driver, not my toy, and I don't have funds to experiment.

a hptuners will run ya 400 these days with 2 credits to unlock your pcm.

Well above $200 from zzp. I don't have $400 to spend.

Same as anyone else. Increase HP. increase transmission life, increase MPG.

There are three things you can do/experience, and it is represented in a simple formula...

Fast/Reliable/Cheap

Place your finger over which one you want and you'll see what you're left with.

Want fast? It won't be cheap/reliable...
Want reliable? It won't be fast/cheap...
Want cheap? It won't be fast/reliable...

Or just know you can only have 2 of the three at any one time, use the examples in reverse... If you want fast/reliable, it isn't cheap!

Those are the universal laws, many have tried to escape them unsuccessfully.

Add to this your are looking at an old platform where everything that has been thought of has been done already. Take heed the suggestions. You don't have $ but want to throw it away on garbage. Good idea! Save your money, save some more and get what works, you'll be much more satisfied. Those chips basically tell the engine it's 10* outside so they dump fuel. Light as we just unplug your IAT sensor and allow the ECM to default temps. Again, more placebo than anything.

In any event, good luck

So what, exactly, makes Superchips garbage and Overkill not garbage? Both are just ECM modifications.

Also, I don't have a GTP anymore, I have a GXP.

Also also, your next to last sentence makes absolutely no sense.

Okay, but WHY is it bull****? That was my initial question. All I've gotten is insults, not facts.

The cortex is by no means junk. It's basically the same as a canned tune for these cars, but you have the option of personalizing a few things on your own.

If you're expecting a noticable increase in power and a jump in fuel economy, you're going to be disappointed. It's a waste of money in my opinion, for a very small gain.

Thank you for the rational answer, but of course, i still have a question.

One of the posters above who insulted the Cortex bragged about his Overkill. Also a canned tune. Once again, what's the difference?

Overkill was a guy that did custom tuning on these cars. But it was still essentially just a canned tune. I wouldn't say it's any better than the cortex and vice versa. Overkill quit tuning the v6 cars. I'm not sure if he still does v8's or not.

Purchasing your own tuner is still the better option, imo. Besides, you probably have a transmission rebuild to save up for driving a GXP.

If that was done before it came to you, priority should be on removing displacement on demand.

The GXP aftermarket is small to put it lightly. It's entirely possible it will get expensive rather quickly and probably still be slower and less reliable then a GTP.
