Dub, whats the work schedule like nowadays? I know we talked about returning the exhaust to its rightful owner. I assume you want to wait until you close so you don't have to deal with it until you get to the new crib? We need a Houston meet soon. I'm craving some chicken wings....

I'm not the injector/tuning master, but I would say it depends on the pulse width. You can keep the timing in check by getting more fuel in a shorter pulse which makes for a more bottom friendly tune. If you are trying to increase the total fuel delivery, then I might go 40s and still keep the pulse width down. CP3 will work better than a CP4 for you so I think you are good from a total volume at 40s too.

Maybe another more sage individual can chime in

That's a KW or Idaho Rob question. What I do know is that if you aren't running huge tunes, you can still plan ahead and run a larger injector, like the 40s and have a very happy motor with shorter pulse widths.

Stock motor and turbo you probably wont be able to increase the total fuel delivery to add a bunch more HP because you are out of air, but you can decrease the pulse width and be more efficient and easier on the bottom end.

It's safe if your tuner knows what he is doing. I have seen a truck with 40% overs on stock engine and trans that runs as good as stock. He has the same tunes I do, just a smaller pulse width. It's actually better for the injectors.
