Default Re: Chip Vs. Programmer

This is a great post...and Hammer is correct. Some "bolt-on" mods are not worth the cash for a custom tune, but some "bolt-on" mods are in a gray area. Installing an aftermarket MAF will pick you up some HP, but the same MAF tuned in will gain not only greater results in HP but retain the smooth cruising ability. In my opinion all cars should be on a dyno when having the OEM program altered.

The flasher is a great tuning tool for the end user, but has some limitations even with a custom tune to start with. Say like I tune your 281 stage2 cam off road exhaust 80mm PromMAF stang. You have a custom base file to play with with the flasher, say you add a upper plenum and a set of 3.73 gears....you are good to go since you have your flasher Now...if you want to upgrade to larger injectors 90mm MAF 9# blower or maybe stroke the motor you would be looking at a new custom tuned base file...just like the old pain staking reburn.

Big pro of any flasher is less install time and the OBD-II feedback!

I would strongly recommend NOT getting a custom chip on a stock app. unless is is an AODE car...no gain in HP, but I have had cars pick up 2.5 tens in the 1/4 buy changing pressures and lock-up.
