Yeah the boost gauges, along with 2 fuel gauges (FASS system and rail pressure), are getting installed over my Christmas break. The trucks also gonna get a Lipe clutch and upgraded linkages at the same time. I'm gonna contact turbonetics since I have dealt with them in the past and have treated me excelent.

80 psi is about 5,5 bar. If both of your turbos work at pressure ratio of 2,55 bar (absolute) your max pressure will be about 6,5 bar absolute, meaning 5,5 bar (80psi) boostpressure. Pressure ratio of 2,55 means that each turbo must make 1,55 bar ( 22.5 psi) of boostpressure. Shouldn't be a problem ? But that's only if both turbos work balanced, that's why you need 2 boost gauges.

At 89,000 miles I shelled out both turbo's. They where replaced under warranty. The shop foreman told me that CAT put out several lot numbers worth of turbo's with defective bearings. I have no idea if this is true or not, just what I was told.

I haven't looked real hard, but I'm sure companies like Turbonetics and a few others already have them available.
