    • Renntech M157 S63 AMG twin turbo V8 with performance package tune prototype results - +20 whp / 40 wtq @ 1.3bar / 18.85psi

      This is simply great to see. Renntech tuned an S63 AMG V8 with the performance package and managed to gain another 20 horsepower at the wheels and 40 pound-feet of torque on top of the performance package on an S63 AMG. The performance package is simply a factory tune offering from Mercedes adding more boost to the M157 V8. The stock motor has 1.0 bar or 14.5 psi of boost. The performance package ups the boost to 18.8 psi. This Renntech tune maintains just about the same maximum boost pressure so the gains seem to be coming from more boost down low as well as adjusting the timing. This is just the prototype tune that was sent to BenzBoost, expect pricing and final results soon.

        BTW, I was incorrect regarding them playing with timing. I was told that this is still preliminary and they are getting gains through changing limiters and some kind of rescaling as well.

        Nice work RennTech! Looking at the conditions as well, it look like it was pretty toasty during the dyno runs with almost 96F!

        I'm terrified to come across all these new twin turbo V8s of MB and BMW!

        Thanks for sharing Sticky!

        Hopefully we'll see 50+ rwhp soon on PP vehicles... Click here to enlarge

        I hope so too but looks like it is hard to squeeze more power out of the PP. Better to just not get it to begin with IMO.

        The RT M157 tune, I think of it more like the SLR 722 GT M155 engine powerband, just a bit more lower end torque =)
