I had a 2.8 with aftermarket turbo and the fuel economy didn't change one iota from standard when I had to push the c#@p out of it all the time. It made heaps more torque and pulling hills was simple. If you cut the boost back manually it will just take more pushing to get it going. Do yourself a favour and just install a boost guage and you will see that the setup you have when pushed really hard will only boost a maximum of 7 maybe 9 lbs and as you get to cruising your boost guage will show 0 to 2 lbs. You see it has a vacuum servo that controls the waste gate which in turn affects the boost delivered by the turbo so if your cruisin your boostin stuff all anyway and it will boost when required. get the guage and you will see Its a fun thing to watch.

THIS is the best boost controller that I have used. The Dawes controller allows the turbo to spool up quicker before it opens the wastgate to maintain the maximum set boost. I also use an in dash needle valve for fine adjustments on the fly. Also, they can be fitted to conventional wastgate and VNT controlled turbos.
