Should I dyno-tune yet?

[Maelfyn]

I want to dyno tune my s-afc for my i/h/e but I'm wondering if I should wait until after I get an AEM pulley. I'm 99% sure it has nothing to do with a/f but I just wanted to check with the people in this forum first.

I know a pulley will change my whp, but I suppose the a/f will remain the same ?? Input please~!

I'd agree with you, but what do I know?:p

It shouldn't affect A/F. All the AEM pully does is reduce the load on the engine. It has nothing to do w/ how the engine breathes.

Anytime, regardless of whether air fuel ratios are directly affected or not, it is a good rule of thumb to dyno tune after each mod is done to an engine. I say wait until after you get the pully's since you haven't done it anyway, and then you can dynotune it.
