Thanks! I am running MT et street radials.

As for the original topic, most will say up to a 100 shot is safe with the stock tune. Anything higher and you may want to adjust timing and fuel.

I don't know of a Walbro pump for a returnless system. Is your car a pre-99 that has a return style system? If not you pump is probably the problem.

Still using the stock intake. No need to change it until I do some more serious engine mods.

Jay C and others running 19lb injectors... Have you guys had any problems with the 19's maxing out?

I know the fuel isn't being supplied from solely the injectors, but 19's seem to be near their full efficiency even on a full bolt on car, and almost certainly a cammed, or heads cam car.

I bought a 21lb MAF with the intent of swapping in the 21lb MAF and 21 lb injectors just to gain a little margin of safety when I'm in the upper RPM's spraying.

Well, that makes me feel better that it's fine on the bottle. I know the amount supplied to the fuel solenoid would be fine, but I was worried about the injector themselves not being able to supply "enough" fuel while spraying, if they're getting close to maxed on just motor... if that makes sense.

No problem. Hope it works out for you.
