moving to interior. no more than 35psi with your mods..I'd think.

0-35 should be fine. If you go 0-60 you can't read it as accurately on lower boost levels IMO.

Probably 0-50 would be best. Certain stacks will go past 40PSI.

how much boost does a stock lly get?

22PSI. Programmers are capable of going up to 30PSI. Harness boxes "fool" the factory boost sensor, so they are capable of more than 30PSI.

If you are just going to run a Programmer and no other mods that alter boost, a 30 PSI gauge would work.

On a similar note if I may....what should the exhaust temp normally be on a stock LLY....pulling and empty...ballpark?Normal freeway driving?
