Well guys Im going to order a boost gauge but idk what to expect.... With everything i have/have planned do you think there is anychance ill be over 30psi? I dont want to run the 35 if im going to be basically maxing it out. But if im not gonna be over 25 or 30 i dont want to run a 60psi gauge either!!!

Check my sig for everything and let me know any questions or thoughts! anyone running a like set up and can tell me psi they are seeing??

Main main concern is the deleted egr with sinister intake, and the to be installed batmowheel.

If your still using your stock single turbo, the 35 will be plenty. Your factory wastegate opens at 20 and with the batmowheel and even a PPE increase valve you may see 30. Any more than that is just hot air on the stock chargers. I've always ran 35psi gauges, except for trucks with bigger or compounded turbos

He's got a LBZ, no wastegate and boost valve dont apply
I did not know that. I need to stop spending so much time with the LB7's haha. Thanks for the info, you really do learn something every day.

Although I never built 35 on my last truck, I do agree when I hit 28 it looked pretty damn cool. Soon to get a boost gauge on my new 01, thinking about digital though. I use a cheapo harbor freight 20 psi boost gauge when I go to the track, just so I know how hard I launch. It would be nice to have one thats actually mounted. But I'm no longer a fan of pillar gauges. I like the "Sleeper" look :thumb

yeah i know what you mean ive always been a fan of the pillars plus mine has my digital DSP5 in it along with EGT so it works out. I think the fact that my truck is lifted with 35s would give off the idea that its slow so no need to make it look like a sleeper! Although i do love the idea and concept of it especially in a pickup

People always look surprised when I get it sideways at 40mph.

Gauges are over 100 a piece.... Might as well do the 35 and watch it spin and then buy a new one later on if I need it right??

I know on my LMM when I had the stock turbo in it I pegged my ISS 40lb gauge. Now with my 4094 even on tow tunes I can snap that gauge around like a whip. Do yourself a favor and get at least a 40lb gauge for the LBZ, a 60lb one wont hurt if you have any ideas of possibly changing chargers.

if you ever even have the slightest thought in your mind in upgrading turbo/turbos go with a higher psi gauge. I have a 50psi which is perfect since i only boost to a bit over 40psi

You can also go digital with a Edge Insight and the expandable pressure sensor
