    • Maximum PSI (Max PSI) S54 / E46 M3 entry level turbo kit tuned on stock ECU/DME nearing completion, 467 wheel horsepower

      The E46 M3 turbo market does not have a large amount of competition but that may be changing shortly. Maximum PSI in New Jersey has been working on an entry level turbo kit for almost a year now and is seeing nice results putting down 467.9 wheel horsepower a nice increase from their preliminary 439 wheel horsepower dyno. What is significant here is not the power but the tuning on the stock ECU/DME and the entry level price point.

      Tuning is being handled by Technique Tuning whose owner is the only person to have a successful turbo kit for E46's thus far tuned on the stock DME. NickG as he is known has produced kits for M54 based vehicles and is arguably the best tuner to make this S54 kit happen on the stock DME. It is not easy as many tuners have failed attempting to do the same.

      Dyno is on 93 octane fuel. Turbo is a Precision 6266CEA.

      This is an absolutely incredible development for the S54 market and if NickG and Maximum PSI pull this off, major respect from the BMW tuning community is warranted. Good luck to all involved! Pictures below.

        Yes it is adjustable via the adjustable boost controller. On the race fuel they manually adjust the boost controller for the higher quality fuel.

        Went 11.07 @ 130.27 4 days ago... Seriously impressive. Also they made 602whp on the stock DME with some race gas and a full maximum psi exhaust.
