Please tell me about your personal experience with Promaxx heads. I'll be glad to tell you about my negative experience with my out of the box AFR 185's.
How did you conclude that tuning hasn't been thought about?
My personal experience with the heads, I put a lot of lube in the box, to help them slide into the trash bin
I concluded the tuning part, through experience........was just jabbing ya, it'll be fine with your tuning
bolt the thing together already, and smash the go pedal!
