Well its not the mods that concern me, it is the fact that I dont have a manual and dont know how it was intended to work in the first place.
Have tried skinnerbox but its not working for me, only newer type engines there.
And it is very true I have to change the "gear ratio"!
Maybe there is 10hp to be found?
Hopefully I will drop a picture in christmas when I can take photos.

The intake is probably from a 190 gas engine so I think that is where problem starts, I got the car with a diesel engine.
Still use the same intake but removed the choke.
When I started the engine I was surpriced to see that rpm went down with more pedal? and then with more rpm went up.
