I need a 4k kit for my truck. Baddd :-laf

I heard bullydog was working on one where we can download it off the internet into our downloaders but thats pure rumor. Anyone know if there is really a 4k kit in the works? My truck pulls pretty hard til about 3500rpm's than it hits a brick wall :{ :{

I thought the mighty cummins would start to come apart at 4300 rpms??



What is the most RPMs the block can handle?

not sure what stock will handle, but iirc, that banks sidewinder cummins engine wound out to 3800rpm as tuned by cummins... so we might be good for that at least... ?
