    This is a technical, and not recreational forum. That's why you don't see things like that here.

    I do say so! I'm pretty sure Chris (or Bill) would axe anything even semi NWS. Even vulgarity is highly discouraged here.

    I'd rather it enrich with boost. If I'm at 20# I want the meth going balls out. But I see what you're saying, I'm making full boost by ~4500 RPM so it's on full blast throughout pretty much the whole power band instead of increasing with airflow.

    I still have the card MAF but only for the sake of IAT. Been spraying through it for years. I'm sure it's really clean.

    My reasoning for the MAF controller was that my fueling needs at 4000rpm and 7000rpm are different given the boost is always the same. Then again, I'm also only using it for IAT control. I just didn't want it dumping a ton down low in order to have the right amount up top.

    More meth! More boost. Shouldn't the title read 879/899?

    Well let's hear the expectation for your next dyno pulls.

    OK so the Auto Adrenaline 850 run made a max of 1.10 g/cyl @ 6500 and averaged ~1.06 after full boost of ~18#. The AA 880 run made a max of 1.22 g/cyl @ 6800 and averaged ~1.17 g/cyl at full boost of ~19.5#.

    The LMR first run hit a max of 1.28 g/cyl @ 5,400 and averaged at least 1.25 g/cyl throughout, max boost was 21.7#. The second LMR run made 1.30 g/cyl as low as 5,000 and averaged ~1.28 throughout. None of these logs showed a boost spike, it was linear throughout and making max boost at ~4,500.

    So it was moving more air with more boost. Must be a difference in the dynos. AA has a DynoCom and I'm not sure what LMR has. I'm at the max of the 2.5 bar MAP and I'm making >2x the gate pressure so the system is maxed out. Increasing the gate spring pressure could yield more boost as well as adding another boost controller solenoid. Adding heads would lower boost and I would need to increase the gate pressure and/or add a solenoid to get back up to the same boost level. Those are cheap mods (not the heads but the gate springs and solenoid) but I don't really plan on doing them any time soon. The car runs well and I'm really close to my goal of 900 RWHP. Just going to drive it as is for a while.

    That seems kind of low....my 402 with 80mm turbo and L92 heads is around 2.40 g/cyl at 16psi, which should be around 800rwhp for me...its a 3bar SD tune though, not sure if that makes a difference.
