The seat-of-the-pants difference isn't earth-shattering, but the wheel spin (auto) is greater, to begin with, and the throttle response feels and sounds quicker.

It's an alternative if tuning is not available to you.
lol. Let me hook up my scanner and show you what your car is really doing and you'll cry. Then let me tune you and you'll ****.

How much is that Jet performance thing anyway? Isn't it like $250 or something?

Sure, come on over. It works and that's all that matters. If you want to fly across country on your dime to prove it more "power" to you. like I said, it's an alternative to people like me that don't have anybody to tune my car.....and just as important, I can just unplug it if there is a problem. JEGS, $239.

Well, I don't know where you live, but there are tuners all over tuning 2.4s for like $300-$400, and most will flash you back to stock if needed for free. I dunno. I give up. Nice pun, though.

After installing the Jet module and running the car in the garage (yes, door open) the difference in smell is considerable -- definitely richer!

I don't want to argue this issue -- if you can get a tune do so. I can't -- and don't know anybody around me that can tune. There are some Corvette tuners local but they don't want to mess with a 4-banger they know nothing about.

BTW...if I "buy" a tune from you will I be able to remove it and sell it to someone else Jet =

The Jet module is tangible -- not just labor -- and I could get some moolah for it if I trade in or sell the car. A very big point.

So, now you are trying to convince poeple that buying a Jet thing is actually better than getting a tune, because you can remove it and resell it? Forget the fact that a tune is custom calibrated to your specific car and wants, will give you more power and better gas mileage then any chip possibly can, can be customized countless times as your mods grow, addresses the specific issues that you car has in regards to timing, AFR, etc... and be tweeked in an almost endless number of combinations to suite your specific driving style. Oh yes, and let's not forget that it is actually possible to get it done for less than the cost of the chip.

Okay, you win. Do what you want. I could personally care less.

Again it is an alternative. Truth is I don't know you but you want me to trust you to "tune" my ECM? What happens if the ECM goes out and GM refuses to warranty it -- will you provide the new programming if I end up buying a new one? There are many pros and cons to everything on this car. I have used and been involved with car owners that used Jet Proms on 86/87 GNs and 86/87 T-Types in 1987 and 1988 and those cars were fast with the Jet proms! Jet Chip is not a fly-by-night company either. The more I drive my Cobalt the better it feels. I am pleased with Jet module!

Jet is a good company. Im shure the piggy back device is great ... However with a piggy back device you can't make as drastic of a change as you can with an ECU reflash the Jet chip only changes a limited number of peramiters. Where as with the VMS tune if your auto you can change shift points and when the TC engagues lean out your fuel for better fuel economy and change the bog time with the vvt.
