Pls don't move it to FI section, need advices from track guys. Thanks!

Hi Guys, my Z will be mainly for track and autox. After DE1 on Sunday, I decided to switch back from SC to NA. The injectors was upgraded to 600cc, MAF and fuel pump were upgraded as well along with the SC, so I’m wondering should I leave the upgraded injectors, MAF and fuel pump or change back to stock (or some brands that really useful)? For the next few years I will stay in DE 1&2, so I don’t really interested in spend $$$ to gain power. As long as the engine is healthy (oil cooler and radiator have been upgraded, so cooling seems good), I will focus more on seat time and safety. To tune the engine back the NA, reflash the ECU should be enough? How benefit you guys feel after get tuned? Next track event will be in less a month, need to get car done very soon to register, your advices will be very helpful to make my decision!

 

Seems like the easiest way, to me, is return to stock and have fun.

 

Just return to stock, no need for your injectors. Do you have a return fuel system or just upgraded pump?

 

R/T upgraded fuel pump instead of ATI in line analog FMU controller.
And just got help from R/T this morning, they can tune the NA with upgraded parts. So I dont need to switch back to the stock ones.
