335WHP Z4M Coupe + shifting issue

[e86nut]

Finally got the Megan Racing Headers on my car. With the headers and the carbon airbox, car is making 335WHP and sounds awesome. Still getting used to that amount of power, its a lot of fun.

I also, during the header install, I switched over to RP Synchromax for trans fluid and now, it seems like I have to use more force for the 3-4 shift. Anyone experience this? Thanks!

What else have you done to the engine to get that kind of whp?

LOL I know its entirely their fault how dare they interfere in my tunnel run


In terms of other mods its just the turner airbox, headers and tune. Also stromung mufflers but I doubt that factors in much haha
