I'm not willing to go all in on a Power Commander and the associated dyno runs and custom tuning, so I wanted to see if there was any current feedback on the use of a temp spoofer and if it helps with fueling and throttle response. I also don't want a significant drop in milage.

I know there is a lot of info on the list, but much of it is dated. The players seem to be Booster Plug (reasonable at $150), and then AF-XIED and FRK at $379 and $293 respectively. Seems like a crazy amount for some resistors in molded plastic for the latter two? I have no idea if the AF-XIED is any different from a regular spoofer?

Any current input from anyone that has added one of these and the effect that it had?

I just have an Akro slip-on and the cat is still there. No header replacement.

Thanks!
