I'm looking to buy the ISSPRO pyrometer. Can someone explain to me the difference is between post and pre turbo install? One gauge shows green at 9 X100 and the other at 10.5 X100 Which gauge would you recommend for my truck? The gauge i'm looking at is R3607VWR or R3607TR, any recommendations? Here the site on the gauges: www.dps-performance.com (http://www.dps-performance.com) I'll also be buying a boost gauge to match and pillar mount them.

Here is something you should read from the Banks web site

Just from what I've learned and read about on this site and others, the Pre- Turbo gives a more accurate reading. I was in the same dillema as you just last week. So I purchased the ISSPRO pre turbo gauge and installed it just last night. I like it.
I got the R3607TR

Thanks for the info.

2000 6.5 SLE> Which boost gauge did you get? The R5613R, 0-30 PSI or R5623R, 0-60 PSI

My two cents is go with the 0-30 gauge as you are not likely to ever see even close to 30psi, besides the gauge will likely be in 1psi increments, and therefore easier to read.

I got the R5611R...The one on the bottom left photo of your link..It reads up to 15 p.s.i. As it is now I am only hitting 10 when my foot is in the floor.Not sure but I may have to change gauges once I install the Max-e-tork and turbo master as I am not sure what boost pressure I will be able to run with those mods .

15 psi should be all you ever need for a 6.5 unless going to a bigger turbo.
