Putting out a feeler for unused powerbox. Billed as adding about 10 hp and 10 ft lbs of torque. Best part is that it also changes the throttle response-kind of like a velocity booster or sprint booster in addition to the added HP and torque. MSRP $275 + shipping.
Selling because I am going to try the 3 stage manifold upgrade and ecu flash on my 528 and I need the cash.
Please make REASONABLE offers for this never plugged in powerbox.
I can add pictures when I get some more time.
I just sold a SSTT to brabusw209amg and I am sure he will give me a good reference. I can give e90post.com and ebay usernames for reference as well.
Thanks for looking,
Mark

Great product. You get HP and torque boost and throttle remapping like a sprint booster or velocity booster - and it costs less than a sprint booster or velocity booster!

 

What is the 3 stage manifold upgrade?
