Ken, I recently installed a 75mm TB on my diablo delta chipped '02 5.4L F-150.

Is it worth it (or necessary) to have the chip re-flashed for the newer TB, and will I be able to pick up a couple more hp?

Others would like to know in the following thread:

Just a throttle body alone won't require it. I recommend it for a larger TB with a MAF change, whether or not the MAF is calibrated for stock injectors.

 

Thanks for the advice!

 

I am now entertaining the idea of headers for my rig, with headers and a new TB, would it be best to have the chip re-flashed?

Man I sure love this power stuff!

 

Well it is for sure, I will have headers on my doorstep in a couple of days.

Any thoughts would be appreciated!

Thanks again!
