I know....

Yep, have the same Snap-On set up myself. I've always used the BG injector cleaner for that. Works really good. Depending on where the two fuel ines connect on the injector rail, you can just loop the supply fuel line back to the return line (assuming ofcourse it has a return, most newer vehicles don't have a return fuel line) as to avoid setting a fuel pump relay or power code in the PCM by removing the fuse. Just another way.....

Also my experience with doubling up on the BG44K in a larger fuel tank, or adding a single can to a half full fuel tank, is that the mixture is too strong and will break up (on higher mileage vehicles) carbon deposits in little chunks, instead of desolving or burning the deposits off. (same results of sucking cleaner through a vacuum hose in the manifold)

Depending on the type of Catalytic Converter you have, (cross comb especially) it will start to plug your cat. Thus resulting in loss of power, vacuum, which can affect shifting...etc.

From my experience it's better to lean out your cleaner to fuel mixture that you put in the tank, and do it through a couple of tank fulls, than to rush it and potentially set yourself up with concerns not expected.
