I have had the 034 ECU and TCU tune in #2 since I picked it up, solid and frankly better than the APR tune I had in #1. Glad to see that 415RS6 has had it for 3 years with original tranmission. Don't need to tell you what the extra power and torque might do. 034 is just across the Bay from me, they initially did the tune custom for one of their clients who had another well known tune in his car and was dissatisfied with it. The dyno report you posted is from his car; I have not dyno'ed mine. I did have them tweak the TCU tune recently, and I suspect it is in all of their outgoing product now, as at WOT I would occasionally find it stuck for a split second before upshifting. No longer does that. The guys at the shop are very responsive. Since they are close to me I had them flash it in the shop there. The price point is also good. You won't be dissapointed.
