Jet performance products jetchip.com has a module you can install, BUT it conects to the map sensor, and throttle position sensor, and adjusts the air / fuel micture. Little to no effect IMO. I have also seen them for the desil engines, but nothing usable for the gas.

Keep in mind that the CVT will override and limit the engine's torque to prevent belt slippage. So if you have the CVT, and you're looking to make it quiker off the line, the gain maybe wasted at the CVT.

Well, that explains why my car seems to have "NO BALLS" when I jam the accelerator pedal at 55 mph. But it does like to go to 6000 RPM... it just doesnt go very much faster any quicker.

I think you better have the CVT flashed with new software. At 55mph, if I floor my SXT, I get a whiplash as my head slams the headrest. Anytime I floor it over 20mph I get that effect. Under 20mph is when the CVT limits the torque.

I'm not sure if this is what you are talking about, but I believe a lot of prior discussion here has pretty much proved that no one has really found what you are looking for - at least one that actually DELIVERS.

Check out the links in the response I posted to this previous thread about performance chips, they seem to reflect what others have found out about these devices:

About the "passing" gear feeling. The early production cars had a switch connected to the gas pedal for WOT downshift.

I don't believe the newer cars experience the same feeling at "kickdown" throttle openings.

Where would I get the CVT in my Caliber flashed with new software, and do you know if it'll void my warranty? :confused:

I second this, my acceleration is nice and strong once the car gets going. It's surprisingly great at higher speeds compared to quite a bit of other cars I've driven. You should have it checked out and get the flash update and see if that helps.

The dealer. It's a TSB.

Thanks. Hey, I don't mean to sound stupid, but what's a TSB?

LMAO! You must have one of those top-secret experimental engines installed by mistake! Or maybe you keep getting rear-ended by a Ferrari every time you floor it! (check your rear bumper.) But seriously, that's great. :cool: Mine was built after the TSB for the CVT so it should be OK, but break neck acceleration is just not going to happen with mine. The engine itself takes a secong just to come up to speed before it starts pulling.
