Josh the owner has asked me to try to organize a group buy of 5 tunes. For this we will each receive a 200 dollar discount on the price.
Take a look at his site and if you are interested post here. The offer is for any e85/86 regardless of engine.

Below is a quote from Josh from z4-forum. Obviously the big power numbers are not NA.
"I’ve yet to find a company that has spent more time or is as dedicated to the Z4/Z4M platform. I’ve owned a Z4 for nearly 20 years, and I personally have a built engine and high boost twin screw supercharger in my non-M, >500 whp in both my Z4Ms, and sponsor a supercharged Z4M Bimmer Challenge car. I’ve tuned Z4Ms to >600 whp on the stock ECU, and I can safely tune the most power out of a Z4M, OTS or custom. I have yet to see a tune I couldn’t beat. There will always be someone cheaper claiming more power because oftentimes these claims aren’t truly challenged in a head-to-head comparison. We claim 15 hp but usually see 20-30 whp."
