What's the deal with the flash???

[1IDSPTTR]

Anyone know what exactly gets changed with the stall-fix flash? I got mine done recently, and gained 2 MPG, and I swear that I get more speed for the same RPM's. Did they increase the timing, or lean out the A/F? I'm curious....

I noticed same so far... higher idle cold and seems peppier. Just got mine done yesterday

I don't know but it sure helped the car run better and faster!!

Yeah, I gained 4 mpg plus the car runs smoother all the way around. At Kenne Bell the software guy worked for days and nights to decifer the new code. He said it was all new stuff.

Did they put a sticker on the plastic shroud showing computer reprogram by chance and what does it say? I had mine done and I notice better start ups, and cold temp(engine not warmed up) driveability.

Noticed maybe a slight increase in MPG, but idle is definitely a lot better.

Didn't notice much in the way of power gain though.
