Power gains:

93 Octane, catless down pipe with stock exhaust - 484 WHP and 367 WTQ
103 Octane, catted down pipe with stock exhaust - 550 WHP and 417 WQ!!!

These numbers were recorded using a Dynojet 224x. Here is the dyno file:



The following graph shows the same exact dyno runs on our Superflow Autodyn30 recorded the same day. We see numbers 6-7% lower than any dyno jet. (This is pump catless and 103 catted)




Benefits when comparing to our competitors:

  • Stock MSS54 ECU tuning
  • Single Bank 02 sensor Conversion (More info on the benefits of that here: http://forum.e46fanatics.com/showthread.php?t=967056)
  • No fault codes stored or hidden
  • Utilization of the the "Check Engine" light (it will only illuminate if there is a real fault in the system)
  • All factory diagnostic checks are functional
  • The catted version will be able to pass all OBDII readiness tests without any "trickery"
  • OEM int
  • The catless version will have no CEL illuminated, however it will not pass the OBDII readiness test for cats and 02 sensors.
  • Our kit produces more power across the entire power band pre pound of boost when compered to any other bolt on turbo or supercharger kit without methanol injection
  • A cheaper more powerful turbo option
  • Our kit utilizes a tubular stainless steel manifold
  • Hand fabricated parts made and quality tested in the good ole' USA
  • The power gains we show are made with the bolt on kit through a full stock exhaust; nothing else is required to reach these numbers!
  • More gains are to be had with additional exhaust modification

I just wanted to write a little reaction post in this thread of my experience last night. Here in Annapolis MD, Jaycent who runs MPACT gave me a call saying his Maximum PSI M3 was ready to be ripped on. So of course I get in my car and rush to get that ride. Let me just say this car is insane! I know jaycent will write his review in detail of the kit but from a passenger perspective theres nothing better than a turbo'd M3. We did a few highway pulls from 60-120/130 range and the car just kept going!! :excited: I had nothing but smiles on my face as did he. The car is louder than I thought and the turbo spools very nicely! You will definitely be noticed on the highway with one of these kits! He has their exhaust system which I think sounds the best out of all turbo M3's I have been in.

I have been a huge lurk on this forum about the different turbo kits and I think this one takes that cake being on the stock DME! Being from Maryland and the emission BS we have to deal with this is the kit to overcome that. I cannot wait until this winter when I send my car up there to get a Maximum PSI kit. See you guys at MPACT Maximum PSI.

The M3 makes more torque than the TT 330 above 5k RPM on pump fuel...then with better fuel the gap gets huge.

I've heard that the TT stg2 330 is more fun on the street though, as it makes more torque under 4k RPM than the M3. All a function of the smaller turbo and intake manifold....
