Re: tbi spacer and injector spacer
I put an injector spacer on my 305 and noticed an increase in throttle response. i don't know how much of an improvement there actually was, but based on the seat of the pants experience, I thought it was well worth the money. Not to mention it is a pretty easy modification to do.

I have the injector spacer and I thought there was a slight difference but who really knows! Its a cheap easy mod to do. I'm sure it helps when combined with other mods like headers at higher rpms.

Re: tbi spacer and injector spacer
I made my own spacer modelled after the one you're looking at and it seemed to give it a bit better throttle response and made my old lo3 breath a little easier in the higher rpms. I think the 15hp gain they claim is a little optimistic though. If you do decide to use it do the ultimate tbi mods with it for the best result.

Re: tbi spacer and injector spacer
What's a good source for new exhaust donuts for the L-69 manifolds?...
