florida tuners?
I've had both my LS-powered vehicles tuned by Jeremy Formato at Faster Proms. He travels and does great work.

When I do a "full chassis dyno tune" as I like to call it, I start with the start up and idle to see what is needed and make necessary changes there and to verify that everything is good mechanically as well as the with PCM and sensors. From there I check the cruise range of the RPM band while "cruising" on the dyno to very the same again. One has to remember that there are several items that need to be addressed during idle and cruise that if left alone can adversly affect wide open throttle.
From there once everything is done or very close I can start on wide open throttle and still make minor changes as needed for idle and cruise. After all is done then a road test is next to verify everything. Sometimes small changes are needed there also.
I am not a big believer in a street tune in that to get tune done well you need to exceed the speed limit several times to get it done. Not tuning driveability on the street is cool.
Also, when tuning on the dyno you can actually see that the car is "happy" with a change by the HP gains and/or losses. If you are on the street and using a wideband, you may have the A/F set dead on for what you think the car wants, but it could be a different story on the dyno and actually need more or less fuel and timing to hit the sweet spot.
Hope this helps.
