I am about to install a used black aluminum Eurocharged 65mm pulley with 11,000 miles of use on my SRT6. I will replace the bearing before doing so.
Are you gentlemen saying that the aluminum one is not trouble free compared to the steel design? I thought that the EC aluminum pulley was the second generation, newest and best. That the first question.

I already have the Eurocharged tune for stock hardware and love it, but when i purchased the tune, they told me that subsequent updates would be $35 each. I had asked before since i always intended to upgrade the pulley. I also have a NA Roadster that is Eurocharged tuned and was told that it came with a lifetime retune at the time of purchase. When it came time to retune after my larger throttle body upgrade (highly recommended for NAs) they wanted another $35 at the time.
Now after speaking with someone at their office they want another $150 to update the tune for the 65mm pulley. Not cool. I have businesses and always honor what i tell my customers.
Now for this question, does the CPU adapt automatically to the smaller pulley or can it be ran without a retune?

Thanks in advance if anyone can respond to this.
