I bought that MTR fuel kit. Injectors flowed 650-620 CC not 680. If that aint an issue then i would say it is great. I have no experience with sard injectors so i cant help you out with them.

im running sard 650's

seems to be running fine on stock rail. not leaning out and allowed me to run a couple psi's more then i could with the 440's. also running with a aeromotive fpr

drop in and readjust with powerfc is all i had to do. i had to bump up the fuel pressure a bit to fix my idle prob but other then that all is well so far.

My 800cc Sard injectors in my stock fue rail did pretty well for my car.

did you modify the rail at all? make it dual feed?


I thought i was pushing the stock rail with 650's
