Boost Pressure

[SouthernSmoker]

I installed my gauges and 18k mod last weekend. With the 18k turned up I can hit 30 psi of boost, is this normal or is my gauge off? My SES light comes on at about 25 psi. I have heard that the light should come on at about 18 psi.

I would say that maybe a little high. As in not saying your gauge is off but that is high for a stock turbo. May want to be cautious with that ok.

[SouthernSmoker]

It just touches 30 then falls back down. What would happen, burn the turbo or burn the engine?

[bigcountrysg]

Uh you can say good bye to that turbo if you ain't careful. first thing to go would be the seals from there who knows.

SES light should come on around 24 psi, then start defueling. Better watch those EGT's!

Yes this is normal youre gauge is probably dead on. I can get mine to hit 30-32 sometimes. The SES light should come on and defuel somewhere between 22 and 24 lbs. You can get a map fooler to keep the computer from seeing the extra boost.

what chips do you guys use because i have a six gun and a big hoss chip, and a banks impeller and intake and exhaust, and i cant get more than 24 maybe 25lbs
of boost.

I'm using a DP-Tuner with exhaust, and I get 25-28 psi with it turned up on the 120 or 140 settings. I'm also using a boost fooler to avoid the SES light and defueling.

I am getting about 23-25 stock havent tried with programmer yet

I can get mine to 29 psi on a LONG uphill WOT. This is with exhaust, intake, and 10k.
