Jet Performance Module

[Red07SSNA]

An alternative to tuning (if you don't know how or don't have anyone that knows how to tune) is the Jet Performance Module. They have stage 1 and stage 2 modules for the 2.2L and 2.4L. I purchased a 2.4L stage 1 module from JEGS ($239) and installed it yesterday. The install instructions are just a generic GM module install and leads you to think the module attaches to the bottom connector -- it goes in the middle of the three connectors. The C1 connector is the smaller top connector, C2 is the middle connector (use this one), and the C3 connector is on the bottom. The C2 and C3 connectors are 73 pin each. One major advantage of the module is that you can take it off and resell it if you trade in or sell your Cobalt -- can't do that with a "tune". "IF" you can find someone that is truly able to tune your Cobalt that probably is the best, the Jet Performance module makes the "average" owner a "tuner".

After install I noticed right away that it runs richer -- can smell it -- and the throttle response out-of-gear (auto) is quicker. Driving the car I get more off-the-line wheel spin then before and the acceleration feels better at part throttle for sure. It seems to go through the gears quicker but I can't prove that yet. Fuel economy hasn't suffered -- my DIC is recording better MPG then before (27.1 Vs 26.9 in-town stop and go driving).

Anyway, for those of you like me -- tuning impaired -- this Jet performance module could be your answer.

I plan on getting the stage 2 actually,next month,it suppose to run real well with any other aftermarket part on the vehicle,even if it has a supercharger or a turbo,

Stage 2 is only ~$10 more. Since 95%+ of my driving is 45MPH or less I went with the stage 1.

If you do get the stage 2 make sure to post about it.

I will for sure,I know they have mass air sensor from jet chip that is suppose to work well with the chip,but I dont know

Right, Jet has a "high Performance" MAF available too. I'm not ready for that yet...the stage 1 module has provided some decent performance gains I can feel. Now I don't fear having a 2.2L next to me at a light;):D

hahah,I might get the high performance sensor,since it should work well with the jet chip stage 1 and 2,I will be getting that chip though,when I order my downpipe next week,I already have the header.I was looking trying to find someone build me a custom downpipe but no luck where I am located,When I get those two parts out of the way then comes next the chip,that should be a nice way of gaining some power.I believe from the stage 1 and 2 you gain about 10 to 15hp

A high flow MAF is like a high flow cat. Damn near pointless.

I talked to a technician at Jet about their "High Performance" MAF (not High Flow MAF). He said it is designed for faster throttle response. I'm not ready to get one as I'm enjoying the Module -- but maybe down the road I'll try it.

Well then you will have to let us know how it goes because I just don't see the point in it.

[burzumaske20]

well at least we know the chip works,but since he has stage 1,I wonder if there will be a difference from stage 2 possible an extra 2hp?
