Before modification engine really shakes, after modification the engine is much smoother, less exhaust smell, faster acceleration Customer reporting that car still runs great but it has dropped a couple or 3 mpg's. any suggestions out there in Gadgetman land, suspecting a vacuum leak???????????? or what? help me out if you have a suggestion or many please

There is basically only one reason for failure. That is, if you disregard the computer's role. That is the vacuum system,

Please contact me via e-mail and we'll see-together- what is happening. Then you can post the results of the process here. I promise it will be worth the effort.
