I've been on Diesel Manor's website checking out gauges. I'm getting ready to pull the trigger on a 3-pod A-pillar gauge set.

My question is this:
Their website offers both 30# and 60# fuel pressure gauge
Their website offers both 40# and 60# boost pressure gauge

Which of the above should I get?

I'm bone stock now. Longer term, I'd like to get a Smarty and get a little more torque/hp out of the engine. But nothing crazy. Probably only 100 ft-lb/40 hp more. So with that being said, do I need the 60# fuel and boost pressure gauges? I'm thinking not, but I'd like some more experienced feedback.

 

Go with the bigger I say. It's cheaper to buy them once than it is twice

 

A very good point, indeed. I just didn't want to end up using the bottom third of the gauge range given my future plans.

I guess what I'm asking is really this: what will be the maximum fuel pressure and boost pressure gauge readings with 1) my bone stock state, and 2) a Smarty installed?

 

My 06 sees 8-10 psi on the stock lift pump (smarty does not change this). Stock boost hits ~27psi, and I've seen as high as 40-42 with any of the three jr softwares on. Typically only see 36psi though. I would go with the 30 psi fuel gauge and 60 psi boost if it were me.

 

I recently installed a Quadzilla Scout II. Wow is it nice. If you want to see what your truck is doing look at this less money easy to install unit. REAL time info. How about the real problem with EGTs is spikes. The scout II is instatanous readings. I like the trans info, show gear and if locked up or not, temp, and % slip. IT IS Awsome.
