Hey everyone,

I hope everyone is doing well. Recently joined. About a year ago, i picked a 550i m-sport RWD. The car has been amazing. After a few months, i decided to do the Bootmod 3 stage 1 tune. Its been on the car for about 14k miles and the car still drives amazing.

Occasionally, ill go to the dragstrip for fun with a few friends. Best i've ever gotten with the car is a 12.1 @ 113. The car feels awesome.

I been thinking about doing the downpipes and uploading stage 2. Is it a major difference between stage 1 and 2? Anyone test it out in the quarter. I see some posts with people running stage 2 and wont even get close to 12.1. What's the deal with stage 2 and what concerns should i be aware of?

Thank you for your time.
