Overboost, where did you find the options you wanted or had the option to code for the e53? I found this list here for e46, and I know some of those will be cross compatible but wondered if you had found a complete e53 list.

Nice info! Very detailed :thumbup:

Watching Daytona and your car running this am. Looking good

We actually never finalized our driver line up to run the 24 Hours of Daytona in the LMP3 class. We bought 2 cars in November, 1 to run in WeatherTech in the 24 and 1 to run in IMSA Prototype Challenge (IPC).

We did run Daytona last week at the ROAR before the 24 as that was the first race of our IPC season. All the WeatherTech competitors were there for practice for this weeks 24 hour race.

Unfortunately, our race was over in 6 laps when our driver got collected in the melee in turn 2 when one of the cars spun on the first restart. There were 19 cars all coming 3 wide and nowhere for our driver to avoid contact. We hit him and then ass packed by 2 more cars behind us. Day done. Somewhere around $70K in damages to a brand new car. Our race was actually the 10 minutes of Daytona. :banghead:

Other than that little issue, how was the play Mrs Lincoln? :)
I watch most of the racing along with 23 other people in the US. Racing was good, the play by play sound to racing background engine sound was pitiful. You could only understand every other word. I wish they would add vehicle/engine type to every graphic on driver race positions.

My wife's tolerance to zoom, zoom, zip, bratttt! is VERY limited. I personally thought it sounded GREAT.

Here is our IPC race last week. Not the NBC coverage we wanted. Oh well, get it back together and head to Sebring. Still up in the air on the 12 Hour but for sure running IPC again.

Hey Overboost,
Love the build! I just acquired an 06 3.0i that's in fantastic shape, I'm installing my advin 4 tomorrow but had a question about the exhaust tips. What was the piping size for the single inlet to match up to the stock muffler? I see you did dual 3.5 outlet tips.

Thank you!

2.5" to 3.5" tips. If you go with the Yonaka universal tips you will need to cut and weld them on so they don't stick out too far.
