I find that video super hard to believe...but as usual, opinion...
Reason for calling BS is that I also conducted a "test" with my stock 335 and the M135...Neck and neck till 3rd where I started to pull an advance really slowly...and I mean SLOWLY...like where you wanna start putting a foot out the door for an extra inch. Did multiple tests on the same evening in this regard and all were the same...?
Same test conducted with the 1M had a different end result, where I'm not willing to disclose the results :yuck:
That being said, there's very little in it if all cars I "tested against" were stock. Despite this, I still think the 1M would come out tops.
