I've heard there both good, but from my experience I couldn't get either one to respond to my emails. I used nelson and love it. Ordered, shipped, and installed before bb responded. Not trying to talk bad, just saying.

Yeah Blackbear is tough to get a hold of. Justin is always out on tuning trips. I live 2 hours away from them and I still haven't been tuned. It takes too long for them to respond to really plan ahead well. Hopefully I can get tuned soon, I'm beginning to add bolt-ons and want to get a tune by mid-July.
