Ive dealt with my fair share of injectors built by most injector builders. Trust me not one is perfect, they all have their share of issues eventually. I'd recommend RCD, Warren, Full Force, Elite, etc etc. You pay for what you get for sure, but Jess' customer service is honestly hard to beat thats for sure, and that alone is worth the hassle if you have to pull them a time or two, that is, in my opinion.
