I live in Colorado and only have 91 octane. Elevation doesn't have anything to do with it. They're trying to keep overall emissions down, so that's why I can only get 91.

That's great - but doesn't change my original point which where running 91-octane in a high-boost situation is a 'recipe for disaster'. You disagreed with that but didn't offer any supporting data other than only 91-octane is available in some areas with high altitude. In that situation run lower boost and you will be fine.

If you want a piggy-back, then JB4 Stg1 or Dinan Stg1 would be fine with +3psi additive.
Else go for a flash with conservative timing/AFR and you will be fine. |

If your worried about octane and altitude I have a solution..
Dont use octane booster as it has MMT and will foul your engine, plugs etc... USE Aces IV .. very little known product.. It increases the oxygen levels in the fuel creating a higher burn rate.. it does not raise octane but it has the Same effect of about 8 octane point increase and lowers or eliminates all knock. Its also very safe, cleans the plugs, lubricates the upper cylinder heads, and extends engine life.. Added to a tank of 93 is better than race fuel in my opinion. You could in theory run a 100 octane tune and high boost with no worries all year round. I was in disbelief, thought it was all snake oil and lies until I added it to my 91 octane fuel in CA and did some dyno runs to compare. Not only were my AFR levels improved and perfect but I also got an extra 15 hp and absolutely No knock.. this was on a 101 degree day.. You only need 1 ounce per 6 gallons.. So a full tank of gas is like 3 ounces.. A gallon of the stuff will last you almost a year. It comes with a small bottle that has measurements. You can keep it in your trunk/glove box and just pour what you need at each tank fill... very easy to use.. Research and try it yourself.. I also run this with 93 octane just for daily driving.. its impressive how smooth the engine sounds and runs..

I've been reading about Aces IV and their oil as well. Lots of positive reviews on both products. Have you been using it a long time? Have you tried their oil?

Agreed 100% I just don't want to void my warranty with anybody else. And I don't trust the ability of plugging in a jb4 to find out. Guess I just do lowering springs and visual mods.

I live in AZ with crappy ACN91 octane. I just bought a used BMS Stage 1 off the forums here and plugged it in. Wow, what a difference for a 20 minute mod. All plug and play, doesn't go into the OBD or anything and simply raises boost a few PSI. Car pulls extremely hard, I did maybe 5 back to back 2nd/3rd gear pulls the other day in 90 degree heat and ZERO hiccups. Highly recommend the BMS Stage 1 for those who want some more boost without compromising warranty/etc. Install/removal is super easy and nobody will ever tell anything has been installedz

Well, all i can say is that my tuner only flashes a software version of my build month and year so that when it gets plugged in, BMW recognizes it as nothing suspicious. Most tuners forget that a carr pulls in and when obd gets scanned they see HMMMMMMM the software is from 3 months ago, thats weird, we have no recollection of that and then we all know what happens. Red Flag. I did not read all four pages in the thread, but what i can say is that an experienced tuner knows how to navigate the system codes and can keep you completely under the radar. just my 2 cents!
