Hello All,
I have a 1988 260E M103 2.6. I have had this car for almost three years and love it. Except for one problem. It is extremely slow on take off.

It is so slow that I will often turn right out of my subdivision and drive 3 additional miles to avoid having to turn left across traffic and into traffic (USA) because I might not be able to get out of the way in time.

I had read on this site and others that the R16 mod is nonsense. But after reading this thread and seeing the values of the resistors and what they do I decided to give it a try and remove it.

There is in my case anyway, a very noticeable improvement. While not a rocket ship by any means, it will get up to speed quicker.

I think the spark being advanced allows just enough torque to get the RPM's up faster and into the power band. I don't think I found any additional HP but I feel I moved it into the lower RPM's a bit where it is beneficial.

Thanks for all the information.
