Message: [QUOTE="B585Ford, post: 944800, member: 5497"] Excellent question. From what I have read over the years, you will get varying opinions on that one. There are definitely some very knowledgeable guys who are big advocates of cutting the PW and running bigger nozzles, but when JD did some testing on that they lost a little powa up top but had more down low and ran a little cooler when cruising with bigger nozzles. He never got do live tuning which may have helped. For what its worth, I am in the same boat, I wanted to duals now, but it just wasn't in the budget. I plan to do pistons before I step up to duals and will probably swap my 15%s for 30%s when I do (and do a cam and different VGT). Since I tow and spool up is important, that is why I decided to go ahead and give the 15%s a shot now....plus I was curious if I could fine tune it enough to get it to make gains. [/QUOTE]
