Hi Robby,
I had the same issue here in Germany.
Wanted Ivan's ECU flash but he wasn't happy with non US or Canadian requests. And I can perfectly understand him, all the hassle with customs and EU regulations, I wouldn't do this either if I was him. ;-)
Apart from that .... I had my sceptisism that, even if Ivan would have re-flashed my ECU, I would have a non-reversible mod, which could get me into trouble at the regular tec- and pollution checks here, I decided to go with the Cobra PowrPro. Along with a V&H twin slash staggered and a Cobra PowrFlo.
I can easily remove all these mods within 2 hours of time if neccessary (I went for the PowrPro over the PCV cause it's much easier to install).
And let me tell you, I'm very happy with my choice. All the effects the folks here describe as ECU flash results, I have as well. Absolutely no popping, good throttle response, no more hopping when cruising at low RPMs.
I'm sure Ivan's flash is a perfect solution and worth the money, but if you can't get it, go with the PowrPro! You'll not regret it.
Dirk.
