My air filter should be cleaned, that has been on my todo list...might well do that over the weekend. Perhaps will regain one or two HPs, who knows
I will also next week get the winter tires changed at the BMW dealer - will go there with a new checklist. Maybe there really are multiple small things...
Fully agree with Roland's view of
JCW cars under performing. My car made 192.5hp/221Nm already last December just after the installation of
JCW kit (without any other mods) on the very same dyno and with the same dyno operator (old image attached). Though this was with 205/45/17 run flat winter tires vs. today with 215/40/17 Eagle F1s - so not 100% comparable.
I have a head and a cam planned for early next year. I would just like to sort out the existing mods before that.
What have others tested with similar setup? About 220hp I reckon?
On the positive side, at least made some progress today - the local guys seem to know their ECUs!
