Hondata

Can I run my GSR motor on a P28 ecu just for a couple day's while Im getting my S300 installed into my P72 to be ready for the tune? Its just a stock GSR with the JRSC on the stock 6psi pulley.Then I will up the boost to 10psi once I get the P72 back and go tune.

Also, another question without starting a new thread.Do I need to upgrade my stock map sensor for 10psi or will I be fine?If so, what map sensor is good and whats not?

u should be fine, set a boost cut at 10.5 just in case.

You will not be able to run on a stock p28 with a supercharger. Since you will be right at the limit of the map sensor it would be a good idea to upgrade tot eh Hondata 4 bar map sensor. It is a direct plug in and will allow you to read more acurately at your highest boost level without being in danger of going off the scale
