Never cared to ask but just bored, ever since I have installed my gsk I have to touch the throttle to start it, cold or warm. If I do not touch the peddle it will just sit their and crank, I read something about the pre boost fueling screw effecting this. Does anyone know anything about this.

 

I know that mine doesn't have that issue, but I also know that the user manual that came in the glovebox of my truck specifically says to do so, and it certainly didn't come from the factory with a 4K GSK. Which doesn't change the fact that you shouldn't have to... I suspect something isn't set quite right in there but unfortunately, everything but the most basic of tuning on my pump I farmed out. Hopefully someone with more hands on will step in.

 

It's a common thing. Moving the afc housing forward depending where yours is can help. Pre boost helps a bit but Id set that for throttle response and not starting. And the star wheel does help as well. Usually I just do it by setting the housing. All depends on your tuning tho. Where you need everything. It's not an issue to have to touch the throttle though. Every performance 12 I've worked on has needed to at some point.

 

Yeah that's what iv been reading and looking up.. figured why not sort thing out while I'm doing all this work, turbo, torch overflow valve, and retuning everything.
