    TRM 325is Dyno Graph

    Met up with Mike earlier today to fine tune my car and get some numbers posted. The boost controller we used tapered from 12 to 10psi up top for this run, so peak hp should improve with another MBC. Regardless, I'm really happy with the numbers and the quality of the tune. Also, it ends up I've been running around with (and still am since I lack boost control) 235hp on 5-6psi. I'm looking forward to turning it up next week.

    Stock exhaust. Traded power for my car being quiet. That and I didnt want to spend money on the exhaust.

    Edit: Do you EVER say anything positive? Jeez.

    Hrm - I dunno I would have thought you could make more with that exhaust, but fair enough.

    That place looks familiar.
    It reminds me of three, shivering, frozen-nerved days/nights
    (without a fuse.)


    Congrats on nice numb(ers).

    100% stock 2.5 liter. 10:1 compression. M50 cams.

    Stock exhaust hurts a lot.

    What would you expect from 12 psi?

    I guess I personally would have liked to see over 300 hp but its not my car - if he's happy thats good.

    Oh yeah, peak numbers, I totally forgot that's all that counts.

    I would personally rather have full boost before 2.5k and a flatter torque curve. As opposed to 300 peak.

    Nice numbers - I bet an E36 M3 exhaust would give you some monster power and cost almost nothing.

    Is this a M50 or M52, and is it fair to say that @ 12 psi you could see over 300 to the wheels with a little more agressive tuning? Mmmmmmmm that is tastey for a stock motor......

    Fun numbers for a quiet stock engine 325! You will suprise a few unsuspecting with that! Take on some e46 m3s!
    Where have I been? Astral projecting.
