Hi guys,
I bought a 2008 135i a couple months ago and started to modify it.
These are the mods so far:
Burger tuning DCI;
Precision Racewerks Ignition system;
NGK spark plug set to 0.22;
JB4 + bluetooth connect kit;
New VANOS Solenoids;
Charge pipe with HKS BOV (to be installed this weekend);
Catless Downpipes (to be installed this weekend).
How much WHP you think I am now (based on your experience) and What else do I need to get close to 450hp?
Thanks much!
