I just installed my kit today on my 2003 400i auto, havent gotten it out yet though, but what is the best settings for the clip and jet size for 2-3000 ft, or should I just go with what the directions say (under 5000 ft clip in 4th position and 132 jet) that is what I did anyways but was wondering if anyone has "fine tuned" it for better performance. Thanks

 

The dynojet instructions as very accurate. Let us know how it does!!

 

I did get it out, seems better, we just did some hunting so no mud or anything, but some steep hills and such, seems to have better throttle response. And keeps speed a bit better on hills.

 

You'll know if you're jetted right if you pull your sparkplug and look at the ceramic area. It should be a clean shade of tan. It it's dark then you need to go down a jet size, if its glazed or bright white you'll need to go up a jet size.

 

Thanks, their jet sizes go in order of numbers?? The lower the number the smaller the jet? Or are they backwards?
