I want lots of things! I NEED a clutch already at 12,000 miles but don't feel like shelling out that kind of money when the truck is still almost new! These new trucks are so touchy when it comes to BOMBing!
Stock isn't so bad. This truck stock makes about the same power as my old SO did with the EZ on it, almost..

Well, there may be a hole in my theory though. Sunday I was doing a bunch of running around and three more times during the day when I turned the key on the FP stayed up around 10psi and did not drop back down to zero. The truck started properly each time. I'm pretty lucky in that mine has only had a very minor rough idle twice with the blue smoke but it cleared up almost immediately.

I lost my LP @ 30k so I have the in-take version now. I would have that Walbro system without a doubt if I didn't have the in tank pump. The website says you can only use the Walbro with the filter mounted LP, correct?
Is the FASS the same way?

I have 2 problems with my truck that I'd like to improve. 1) the smokey startups with low FP. 2). My truck hesitates during acceleration when it shifts gears unless you are giving it a pretty good amount of fuel via the go pedal. Like the other poster said, these things are touchy about mods. I have a TST PMCR in my garage that I finally decided to remove because my truck was throwing codes and going into limp mode. I didn't trust it. I like what I read about the Smarty but I don't know enough about it. I assume it adds pressure, which isn't really good for the injectors on these HPCR engines from what I've read. Decisions decisions.... I must admit, I feel much more secure now that I'm back to stock.
