Definitely no beef with Dinan. Happy with bump in power I get from their piggy backs and with them standing behind/warranty. Authaus(Steve dinans company) is only other company that offers same warranty, just not yet for our car yet. My "beef" or issue is I've yet for our exact engine, seen a tune that shows a dyno tune before and after. Everyone seems to go from BMW's number to what the tuner gets out of the engine. As a consumer, I would love to see a before and after, period. Not tune verse manufacture claims, not "oh on a hot day we pulled this #"

My beef is with #'s front and back. Am I the only one who wants to know really the actual power base line and gains per tune?

I've seen dinans web page, post and claims. My car isn't putting out the numbers stock they say it is. That's why all the reviews are vague for the initial 606hp claim, and revised to 590 hp? Put my car against a new M5 on 1/4 mile, half mile and it's clear. That's all
I don't like people being misled by marketing. As a consumer I'd love some actual facts, I think we all would.
