What is required to run Stage 2? Would love to see some customer dynos of stage 2 with supporting mods to see what the HP/TQ numbers look like.

At least a downpipe and probably a simple intake.

Was this ever answered? What are the gains with stage 1 if we are already at 355 hp?

I actually finally got my file to flash but it didn't work because I'm on elder Gxx firmware and Alex needs to tweak the Flasher to get it working properly. I need to go in to his office this weekend if I can find the time. Luckily I'm in SoCal.

Forgive me if this has been covered, but the thread is pretty intense. I'm a total noob and have the 2018 X3 M40i. I saw the Dyno you did, but the hp/torq on that car is different than our B58 (Dinan recently released a Dyno) and with ours being x-drive as well...can you explain how this tune might impact our car differently (for better or worse)? I'm assuming we will lose more from crank to the wheels with the x-drive? I am looking for a solid tune that will be smooth but offer the best hp/torque gains as well. No other mods to the car yet, M exhaust on, etc. I wasn't super thrilled with the recent Stage 1 Dinan numbers of 30 or so hp/torque and wondering if you think we could see more than that with the MP tune? |

Why would it not pass? If there are no CELs I can’t see why there would be an issue.

#1: Some states actually sample the gas coming out of the exhaust, so even if your tune says all is good, it may not pass the physical test. #2: Most tunes that handle a catless/high flow DP suppress the CEL, they don't set the readiness code that says the cat is detected and functional. I think this is for legal reasons - it's illegal to provide a 'defeat device' that lies about the state of the emissions hardware. But suppressing the CEL on a 'track only' product is fine, as long as it doesn't lie about being road-worthy to the electronic scanners. |

Spacers have not worked on these cars. If you have a stg 2 tune and tell them you have a high flow cat they really have no reason to suppress.the CEL in the tune. In cases of tuned cars with high flow cats I have not heard any reports of failed NY inspection. I did not see where you specified catless dp and tune hence my response. However I think we are in agreement on most points.

For.this tuner's(MP) B58 tunes I guess I am assuming that is the case. In NY I have never seen gasoline inspection in my 30 plus years of driving and owning. A sniffer For high CO2 and NO2 Emissions yes which is perhaps what you mean. Perhaps we are saying the same thing but gasoline would be under emissions ,no cat or damaged cat/muffler and other car equipment would be under physical.

So this all begs the question - putting a DP aside as its questionable always whether you will pass, will it pass the basic inspection emissions tests (ie computer hook up and exhaust probe) without a DP - Stage 1? Stage 2?
Maybe MissionPerformance can shed some insight.. Quote:

I brought up high flow cats because catless dps and not passing emissions was a no brainer tuned or not.I did not see where you specified catless dps so thats why I mentioned passing emissions with a high flow cat. No arguement because I think we agree on most points.

Am I paranoid for being hesitant on this and wanting to wait and see if any issues arise with transmission or maybe another "weak" link?

All joking aside these ZF 8 speeds are pretty darn robust (assuming you are 8AT) and this model used in our 340's are used in many vehicles that have tuned the piss out of them. For reference the 335's have had this transmission for awhile that even has a lower Tq rating and they have been running those well above normal flash tunes (upgraded turbos, E85, meth, etc.) The weak link becomes the overly soft suspension and lack of tire under the car. Factory 255's don't cut it all for this power level. |

You'll be pushing the factory turbo outside it's efficiency zone before you start having to worry about the factory AT. If you run a PS2 turbo and E85 or something then I might start thinking about that. Stock turbo power levels not so much. The factory 8HP45 and 8HP50 have been pushed pretty far and across numerous platforms and you rarely if even hear the 8AT fail, they are robust.
