Thankfully until today it has held on solid.
I think your right. My 250 never did it but I noticed it right away on my F within the first couple of days. Great video btw, can't wait to get my headers on!!!

nice vids man! i remember when you posted the first one way back when. my hood moves a little, too. you can easily check it when the car is parked, hood up and it'll move a little up and down. i'll ask the dealer about it next time i'm in there. never really cared to have it "fixed" bc i rarely see triple digit speeds.

Dynapack seemed to read higher than others, solid numbers still though.

To OP, yes result is very much the same when I play with an E92 with exhaust a few times. I also have headers and exhaust

I agree. I have done some pretty high speeds in my F and have never seen that. That could be extremely dangerous. I would get it checked then have fun seeing if it was fixed

I think your lying man for whatever reason. If you watch the other vids on your YouTube page it shows you had ppe headers and the same m3 with the same exhaust and you guys were neck and neck. So by you adding an exhaust you can now beat him by 10 plus cars? Did you leave out the 150 shot from your mods list?

I was going to ask the same thing...looks like the exhaust itself made a HUGE difference then...

I was thinking that's too huge of a difference just for exhaust mods. I noticed a difference after installing my exhaust but that's insane!

I've posted this graph before. Not my graph, BTW, but IMHO, it's a good indicator of the RWHP differences with various mods on an ISF.

Impressive results OP! The difference is definitely there and your video comparison sure shows it. My numbers back up my results, but this comparison shows it much better.
