Customer: Mike M.

Car: 2003 Chevrolet Cavalier L61 2.2L Ecotec


At the moment, Mike’s 2003 Cavalier is completely stock minus the tuned ECU. Even in a completely stock car, there’s lots of improvements to be made. You have to remember, the J-body was targeted at everyone from first time car buyers to retirees… there’s lots to tweak inside that computer to get it driving the way you want it.


Innovative Tuning ECU flash.

Short ram intake.


Mike asked to have his car tuned to run on 87 Octane.

Virtual Dyno results. 128 whp & 123 ft/lbs.  Assuming a 20% drivetrain loss through the automatic transmission, that translates to  160 hp & 154 ft/lbs at the crank, a notable improvement from the 140 hp & 150 ft/lbs of a stock L61 Cavalier.

Customer’s Comments:

This is my 2003 Chevy Cavalier z24 4 door. As of right now it only has Shane’s tune, But it has made a hell of a difference already. I hope to have future modification done to it.

Update Oct. 5, 2013.

After years of good reliable service, Mike has decided to retire his Z24 & has sold it.  Hopefully the new owner will have many more miles of good service as well.
