I have a lt8s on my turbo 2 and latelly I'm been having some issues with my stock tps not working right. I was thinking of getting another stock one but I just wondering if I can be able to use like a GM style one or similar tps with a s4/5 setup map or I need to get it reflash to accept it? Thanks

 

You can use any TPS you want without any firmware changes. You could even use a switch since unless you have set your throttle pumps to trigger via the TPS, the Microtech only uses the TPS to detect on/off idle.
