The MS3 is turbocharged, which means it is easy to make more power. Just add boost, fuel, and timing until you reach the threshold of detonation.

This is the reducer I used for the airaid intake. It goes from 3.5" (diameter of the airaid intake tube) to 2.75" (diameter of the stock throttle body inlet)

Pick yourself up some of their T-bolt clamps as well. They work way better than your typical worm-gear type clamp and help to ensure a tight seal.

I will try to make a separate thread to post this info and some pics to help out others as well. My installation went very well.

I personally have datalogged vehicles with stock tunes - with modifications no less, that were almost 11:1 at upper rpms. Being that rich is killing power, and wasting fuel. You can add quite a bit of timing advance if you are willing to fill up with premium, or E85 if your PCM is ethanol aware.
I would have to agree and I also am not 100% sold on these numbers. But I believe there is some room for improvement and am willing to give this programmer a try. Unfortunately I will not be able to provide any actual data for comparison, but I will give an honest real-world review when I go for this. Hopefully in the next week or so.

There is definitely room for improvement. I would bet money that the Hypertech will be an overall better tuning program than the JET, even if only because it has the ability to be reflashed to a regular octane calibration.

The real benefit to these programmers is that they are really the only way to make use of more significant modifications like TB porting, modified intake manifolds/camshafts etc.Modifications like those will greatly benefit from hotter spark maps to retain crisp throttle response and not lose anything on the street driving side of things. With a conservative tune, when you start opening things up, you risk the possibility of the powercurve falling flat on its face until upper rpms.

Sorry i couldnt PM you back... new member here. Did you see any significant gain with the Stage 1? I'm not looking for any increase in MPG just want to put a little pep in my step in the lower rpms.

Re: Is the Jetchip a complete waste?

Yeah it definitely helped. not as good as a tuner but for the money it was worth it. That with the K&N helped noticeably in the low end. On trips to Vermont I was averaging 23 mpg (evic ) before the larger tires.

The JET stage 2 from autoanything fits? I can't find a chip anywhere that says it fits on an 05 3.7L

Re: Is the Jetchip a complete waste?

Go to autoanything.com or call JET.

But I'd only get this if you can't get the SCT or Hypertech

Re: Is the Jetchip a complete waste?

most say the jetchip is no good because after a short period of time...the pcm relearns or overwrites its changes rendering it useless

From what JET Told me, this is false. If the PCM could reset itself programmers would be pointless.

Re: Is the Jetchip a complete waste?

of course they are gonna say that....but the Jet is a piggy back to the pcm where the sct, superchips, diablo completely erase the stock tune and replaces it with a custom or can tune. Theres nothing to overwrite from the stock tune. They are FULL OF CRAP!
