    Can anyone tell me what a safe boost range would be for the 2.8? I have stock intake and exhaust and won't be changing those out anytime soon. Is it worth trying to tweak the boost on a stock setup or wait until the snorkel and exhaust get fitted?

    Just increasing the boost only increases air flow which will reduce smoke and give a cleaner burn but not much more.
    You need a free flowing exhaust and more fuel to go with the increased air flow for more power.
    a free flowing exhaust should result in slightly higher air flow throughout the load range (turbo spinning up quicker)
    However there come the point of diminishing returns when more air means higher air temp and no more gain, so a better air intercooler cooler adresses that
    and possibly more power sooner, you can spend lots for little gain.
    If you plan to do a lot of high load running (towing of heavy loads) then the cost can be apreciated as economy improves (less smoke more complete burn fuel drive vehicle not just up in smoke)

    Thanks again, Joe. As have switched over to a mechanical injector pump, winding a little more fuel to it won't be a problem. It already runs a bit on the rich side, so I might wind a little more boost for a better burn and see what that does. Not trying to make a race car here, just want the ol' engine to run as efficiently as possible to prevent problems down the road.
