I've seen plenty of M54's with those mods on E46Fanatics or ZHPMafia or on the E39 boards at Bimmerfest - which is why i asked.

Dinan no longer makes their cold air intake or exhaust that I can tell for the M62 so there are no specs on that. The Stage 3 software is for use with the throttle body and optimizes it, I'm not sure it gives more power.

So going off stage 1 software per Dinan website:
-9 hp and 11 ft lbs

High Flow Throttle Body:
-Rated at 8 hp and 8 ft lbs

Since Dinan doesnt have specs on their intake I used AFE's - they claim 10 hp and 20 ft lbs

The exhaust I dont have any specs I can find or any comparable exhausts for their power numbers - so based on the above you can estimate approx 30 hp and 40 ft lbs at the crank added from the mods. And that took me all of 5 mins in a Dinan website search and AFE website.


Sarcasm is the nuture of a forum, especially with new members who's first post demands answers. Please put your year/make/model/engine type in your signature like the rest of us so future inquiries are helpful - and lose the microaggression / trigger words attitude from Seattle - it doesn't suit the forum well.
