Normal highway driving conditions; no load, 65-70mph.

1. What's a good "rule of thumb" to keep the Boost and EGT numbers under?

2. What's aprox nrs are getting close to "danger" levels, so I should aware of if approaching?

I have a Quadzilla Commander; not thrilled with it, but...that's what I have. Basic stock except for the BHAF and Raptor.

 

usually depending on your truck i would say 650-750* empty maybe it all depends. max egt where i start backing off at is 1250*-1300* and my probe is pre turbo but i cant remember what is danger post turbo. my boost stops at 20psi boost no matter what. hope this helps...

 

Thanks! My "Commander" shows my boost exceeding 20psi fairly often; 'specially on inclines at about 68mph-range. Not quite up to 30psi, though it approaches. My EGT gets up to close to 1000, but not sure if I've had it to much more than that. Generally, in the 700-950 range.

Not sure why my BOOST would register so high (+20)...that's without a load...

 

I think the stock turbo shouldn't register more than 20-23psi or your wastgate might be AFU. I've got the Commander too and all I can say is that it works. Not the best, though.... I see 700-800 degrees at 70mph. I set the Commander to warn at 1250 and start to defuel at 1400, I think.

 

Thanks--will research "wastegate". -D

 

Stock turbo i would say anything over 30psi and your starting to get in the danger zone! EGTS When pulling a trailer i would say 1300 is the max that i would want to run, but its not hard on are trucks to run 1600 degrees as long as its only for a couple seconds! I peg out a 1600 pyro when pulling!
