Since I've done my research here on this forum I will also post my results. Bought directly from ESS and shipped to my place in europe. All went well, when I informed the new VT1-550 was just out for my E92 M3. Installed last week, tested on the dyno today. E92 M3 2008 manual gearbox with our local Shell Vpower 98RON and OEM exhaust with first cats deleted.
605hp, 562nm. 525 whp. One happy customer, very nice feedback and correct shipping. Keep up the good work ESS!
