550's or 650's

[wishful_laser]

i am about to the limit of my stock 450's and want to upgrade but i dont want to upgrade to 550's and have to worry about running them to their limit and have to upgrade to 650's when i could have just upgraded to the 650's in the first place. my mods are in my profile. my data logger says my inj.d/c is at 96% at wot through 6800.

650's. No reason not to.

I would say 650s depending on your goals. Only thing I would worry a little about is having the 650s with only an S-AFC. Might be a little tough to tune. You would probably wanna look into getting your ECU done at the same time.

kinda of a stupid question but what ecu modding are you talking about?
