I'm not sure, but I don't think so. The boost-a-pump will just up the current to the fuel pump, but since your truck is a returnless fuel system, the FPR right back there with the pump. I'm not sure what running the pump harder will do against the FPR.

Akly Control makes great kits, as does Snow Performance. Just make sure it's a progressive kit.

 

Where are you located at? I have HPTuners if you are close enough to do some logs. Where is New Freedom?

 

It's by the MD/PA line off of intersate I-83. Around the York County area.

 

Hmm, ya I dont think that is close. How far from somerset?

 

It looks to be about 4 counties across. Maybe a day trip for me, I appreciate the help. If I can't get squared away in the next couple of days by the local speed shop I will send ya a Pm.

 

I'm not trying to discourage you with this comment, and I am a fan of the STS, but your truck is prob. over 6000lbs, closer to 6500. I wouldn't expect that you are making anymore than 7lbs of boost, (which isn't all coming on at mid throttle or going up hills on the beltway) and would think that would put you somewhere around low 14's. I don't think low 14's are enough to "throw anybody back in the seat". It should feel strong, just not like an 11 second car. When I first used nitrous on my car years ago, I was expecting an "afterburner" feeling....when all it really felt like was another set of secondaries opening up on the carb., and that was with a 125shot. Maybe you are expecting to much from a truck that size. With that being said, I would do the boost gauge before you do anything. See if you have boost, if not, it's prob. an easy fix. If the boost gauge is showing that you're making boost, it is what it is. I wouldn't expect the Denali with the STS to run much better than your 300, if it's a Hemi. I'm sure Jason would ride with ya and log some runs, to see if you are experiencing K/R, before you rush out and buy a meth kit or intercooler. I don't know if you are disappointed with him, or the truck, or what, but he'll help you out until you are satisfied. Just give him the chance. I thought he went above and beyond the night he installed it. Plenty of people would have told ya "sorry about your luck" on the bad PCM, but he messed with it and swapped out some sensors until he knew it was the PCM, and then threw a quick little "something" on your factory PCM so you could at least drive it. Most people don't want to get that involved, especially when you didn't buy the parts from him in the first place. Did something not go "right" @ FBC, or is it too far from home?

 

I'm meeting with him tomorrow to do some loggs and see what's up with this thing. I like the work that he does but he didn't do the install. The whole way home I heard rattles and noises. I took it to my regular mechanic and he said a few bolts were missing and I had to pay him to adjust the whole system so the hood would close properly. Not knocking Jason's work like I said, I just wish he was the one working on it and not the new guy.

 

Let me know man... Ill help you out if I can but like others are saying you need some guages to know what is going on.

 

We are going to hook up the boost gauge it came with and see what's up. Thanks for the offer I might take ya up on it later.

 

Zippy, why dont you like the STS kits, they have far more potential than the RADIX kits that you seem to push?
