Hello all, been sometime since I've made a post. Have an update for you about our aftermarket power adder tunes we now offer for the N52

2011 E89 Z4, Auto
Stock Exhaust
3 Stage Intake
ESS SuperCharger with 115mm pulley

Before: Canned tune
After: BPC PowerAdder Tune
(sorry for the odd line at the start of the pull, the tach lead on our dyno has been messing up, new one on its way)

correct if I m wrong , but power adder tune only applies for the people with ESS supercharger right.

Nice gains. Just when I get tired of my car, you come up with something else that opens up potential path and makes me want to keep it.

Slightly off topic. But any updates on tune for milvs?

This is for ANY type of power adder(NOS, supercharger or turbo) I Might also work on a NA E85 tune if it makes any power.

Love how the supercharger evens out the torque curve! How many pounds of boost are you running?

You could have gotten the exact same numbers with catless headers instead of the supercharger, resulting in added reliability over the SC kit. Is that something you may do in the future?

That's awesome. I still want to one of these motors put down similar numbers without boost.

huh? you aren't getting 290whp with just headers. or do you mean with the baseline ESS tune?

oh right, I completely forgot that the dyno is measured in WHP.

Would you say that 340 crank HP (roughly how much power he is putting out) is the limit for the N52 on stock internals? or would you be able to add catless headers on top of that as well?

would you add a longer final-drive after a bump in power like this?

[hassmaschine]

no, I wouldn't say that - did you miss BPC's 519whp turbo post?

Well, with him being banned for so long, he probably did.

those are a lot better than the advertised hp numbers it's associated with.. If then can release there kit with out the tune, then this would be a much better offer. Who's next?
