The jury is still out on the performance of this Kit. It is pretty new, so we don't have a bunch of data as to the performance, but it is really really similiar to the other generic 70 kits. DMP, K-Star, Treats kit, and Airsal. It is basically a generic but quality kit for $77.00 It is fine to just bolt up, but it is cheap enough that you can really play with porting on it.
As for not too happy with out customer service, I am sorry to hear that. We work really hard to keep you the people happy, and on the road. We offer free tech support via our toll free number, and have been doing it for 7 years now. If you ever have a problem we bend over backwards to make if right for you, so if you need something, don't hesitate to call. We try to keep as much instock as possible, but don't have the budgets of some of the other companies out there. If we don't have it stock, it is usually something we can have come from a distributor to you at no extra cost.
We are just trying to get you quality parts at a fair price, and hopefully having fun at the same time. So, to all you folks that picked up a kit already, please right a review on it on the product page. That is probably the best way for all of us to learn the ins and outs of this and all the newer parts.
Thanks for your support!
