    Pressure check the intake. My guess would be an intake leak or turbo vanes stuck if it's a vgt turbo, but we have all gray motors no mp.

    Mack dm vs granite

    I won't say that 1 is better than the other, but the glaring difference is the space in the cab. Unless they changed something, the last dm I was in, was an 80 something model.

    Pressure check your intake for leaks, and put a boost gauge on it. A boost gauge is fairly inexpensive and easy enough to install, and will help you diagnose issues.

    AMI 370 power increase

    $1500.00. On the turbo.

    Hopefully that is ledgible, all the injector numbers to get you whatever you need. Thanks to mackpro. Or mack tech, I can't remember which one I got them from, but they both have been a HUGE help to me and a lot of people on here.

    No, we have been so busy I haven't had time to take it to the dyno. But it's on the to do list.

    I have a ami370, put on an etech exhaust manifold, went to the 427/460 injectors from k&s thanks to mack tech and they were great to deal with, and had the local turbo shop build an s467 with a billet wheel. The truck makes 44psi of boost and runs like a monster, fun to drive now.

    What turbo do I need? AI 460. Etech 460

    The good fuel pressure doesn't mean that there is not a problem with an eup. I had a loader that was hard starting, replaced batteries, tried priming it, did everything I could think of, nothing helped. Then the starter went out, the bearing on the gear on the flywheel side was worn slap out. Causing it to bind and drag just enough to slow it down, but not enough to make an audible difference. Replaced the starter and it fires off fast now. We have never had that problem with a truck, but you never know.

    The 427 and 460 injectors are the same, no difference between them. With a miss and hard start makes me wander if it's an eup.

    You need to put an etech exhaust manifold on it with an s400. But, there are a lot of setups/options with the s400. Best thing is to find a good turbo shop and have them set it up for what you are trying to accomplish.

    I have been really happy with it, nothing like catching a cat powered pete or kw on a hill or at a red light and then running away from them as they look at you in bewilderment. One of these days I'm going to get it dynoed again and see what she is really doing.

    04 Granite CV713 with a e7-427?

    Mack tech has everything you need to know to make it run, in that post. I say that from experience.

    S400 Turbo too big for 1991 E7-350????

    If it is a good deal, I would buy it and put it on.

    Transmission swap

    Yes, but it is not cheap. Last time I looked into it, it was going to be around $25k to do it.
