i also had a rpm/mph question. i have an '88 190E (2.3.. stifling 8V) and at 3500 rpm i'm going about 70-72. if i go up to 80 (mach 1 for the 190E 
) it hits right around 4000. is this normal?? i also read on here about a timing retard resistor. does that apply the the 2.3s too?? can i try and remove it or should i find/order the 2.4Kohm (do i have to go to the dealer for that??).
thanks.
