I'm about to finished up with my built and install the Greddy TT kit. I had TN flash for the TN kit before and now going to flash it back to stock. I will be using Utec with RC 750cc injectors. I would like to ask if I need to flash my ecu to have it scale for the 750cc injectors or just flash it back to stock and the Utec can scale it? TIA.

You should be able to just throw the UTEC on and go without reflashing to stock. I've heard of some people claiming they had issues, but I personally have not. With the reflash at least you get rid of the 155 mph speed limiter and have a higher idle.

By the way, I'm running the UTEC and RC 750cc's as well. No problems.

 

Drop it in, and just tune with the UTEC. No reason to relfash to stock, that I can think of.

 

Thanks guys! I was afraid of the point where the Utec did not take over yet during the ECU is controlling everything and with the TN flash is being use at that time. I will just throw in the Utec and tune it for now. If any problem arise then I will flash it back to stock then. Thanks again for the responses.
