Old thread but just installed a weapon-x port TB. I have terrible stumbling and got CEL and limp mode. Turned car off and got it out of limp mode but still stumbles and tries to cut out once above 3000 rpm. Know its a Z06 thread, but installed on 2017 GS. Any suggestions? Thanks in advance.
Can you reinstall your stock throttle body and verify that the issue goes away for me? If it does, we will send you a replacement throttle body immediately along with a return label for the one you just purchased.

You could always ship the car. We have cars coming in from all over the country. One on the way from FL now.

Normally if the maf is "live", meaning battery is still hooked up and you unplug it, that will cause problems your next start up. CEL etc, but should eventually go away after a couple of miles.
With a PTB install, you don't need to unplug the sensor which is why i said it stupid question but i figure it couldn't hurt to ask.
I had my katech PTB on for over a year now, 6k miles and counting and no issues whatsoever. I even have a BMS and a borla xpipe. No issues whatsoever.
But then again i have a '16 and i know 15-16 are the most forgiving when it comes to these mods.
