    Also fun fact of the day, changed on the dyno from a 3.5" MAF reducer and the stock ASC intake boot (with ASC still in place) to a silicone 3.5" to 3" smooth intake boot. No tuning changes...

    Are you saying that the aftermarket part lost 4 HP on the top end?
    Interesting.

    Thats pretty significant! Im not sure what the ASC boot is, but Im guessing its the original rubber one.

    I think you'll have gotten a client out of me for sure.
    Thanks! Look forward to working with you. We try to pride ourselves on transparency and backing our work with data vs most of the competition :)

    Few Notable Updates. Retuned an earlier E46 M3 after adding headers
    Pre/Post headers, no tuning changes


    After Retuning


    Progression: Stock Tune, Tuned, Then Tuned with headers


    Also retuned an Alum block M52 E30 after it got headers/a nicer exhaust setup

    Tuned a GTS racecar today. Fresh S52 Build, M50 manifold, Headers, Stock cams with timing tweaks, BW race exhaust. 3.5" MAF had to get slapped on at dyno as stock MAF maxed out at ~6500... Stock Injectors. Was running M52 stock tune when it first came in.

    Retuned a car GTS car i had already tuned as OBD1 after converting it to OBD2, no other changes. S50, 3.5" MAF, 24lb, Ebay Headers, BW race exhaust.


    Retuned a OBD2 S50 swapped E30 M3 that had a TRM off the shelf flash on it. Has some weird aggressive cams in it that were doing some crazy stuff. Didnt make any power though?

    Lol. tough crowd around here. Just was trying to prove a point. The power band is less than ideal in many respects and a certain shift point would be ideal under many circumstances. This car sees track too.

    yeah it also makes 400whp at 3600rpm, running it to high rpm just hurts parts and you'd end up going slower in this case
