More great DI-only E85 results with our S55 Lift Kit package! Thanks to our innovative approach, this kit is the highest flowing and lowest priced S55 HPFP solution out there. On top of that, its the ONLY kit that works on the stock tune for all necessary emissions compliance! All we need now are some much larger injectors to see it's true potential 💪 Reposted from @abperformance.ge Solid build. Another S55 tuned via bootmod3 on CustomROM with flex-fuel, map switch, rolling launch, and all the cool stuff. Here goes the modifications list: – Kratos KRAS55Bi Turbos – AR Design Hi-flow Catted DP’s – BMC Drop-in Filters – NGK SILZKBR8F8S Plugs at .020 – Zeitronix ECA-2 – M5 EU5 Injectors – Dorch Engineering HPFP Upgrade – Precision Raceworks Stage 3 LPFP Car runs solid and makes healthy 700+ whp safely and without any extra stress on the injectors and the fuel system. #ABPerformance #ABPTuned #ABP #bootmod3 #bm3 #customtune #customrom #bmw #bmwm4 #m4 #f82 #m4f82 #tuning #bmwtuning #dorchengineering #KratosTurbo #zeitronix @protuningfreaks

Reposted from @f80paul We are very excited to share these awesome results using direct injection only! PS2+ E85 with EU5 injectors and the new @dorch_engineering S55 Lift Kit. 711.71 WHP and 673.72 TQ . . . Customers words - “Welp I just wanted to quickly share my dyno tune sesh result with the maestro Paul Johnson! 🙌🙏 This was the last run after ~ 10 or so pulls as we worked on the 93 map prior in pretty hot/muggy 90+ VA weather😅 DCT F82 PJT E85 tune PS2+ (redesigned 2020 version) Dorch HPFP kit F10 M5/EU5 injectors NGK 97506 at .019” VRSF DP’s AA single midpipe AA 3can muffler Stock LPFP, stock cooling and stock intake with drop-ins 👀 That’s essentially all power upgrades wise. Less is more 💪 No METH or PI! - I was not interested in any potential risks and complications associated with supplemental fueling or secondary controllers. These results were made at “only” 27/28 psi with no issues with fueling limitations. Stay tuned my friends 🤙”
