    • Maximum PSI Stage 3 E46 M3 stock DME tuned turbo kit shows over 800 horsepower

      Maximum PSI as many of you know has been hard at work on E46 M3 turbo kits tuned by Nick G of Technique Tuning on the stock BMW engine control unit. We have already seen 697 wheel horsepower from their Stage II kit on a Dynojet and now they working on their Stage 3 (with a Stage 4 coming as well) built motor application and on a Superflow Autodyn chassis dyno the result is 809.2 horsepower at the wheels.

      There is definitely more to come but so far early on Maximum PSI and Technique Tuning are showing the ability to tune built motor S54 setups on the stock DME which nobody has successfully done. Yes, it's not easy.

      The second graph shows Maximum PSI hitting ~18 psi of boost on pump gas for 660.8 wheel horsepower. It will be interesting to see the Stage III on a Dynojet. Keep in mind, with dropped compression on a built motor one generally will make less power per pound of boost than at the OEM compression ratio.

      The turbocharger used is a Precision 6466. The fuel is MS109 for the first graph and pump gas for the second graph. The exhaust system is a 3.5 inch design that is catless.

      BimmerBoost will of course be watching closely but this is a great start.

        He's referring to their E36. Their E46 is well on its way though with some great ET's.

        Yep this is all correct. Both cars are impressive but the E36 is the fastest BMW street car in the USA I believe right now.
