I was the first ECS kit installed (also by ECS) and everything has been great with this kit no regrets or problems here after many miles and over a year of being on the car in various racing/daily driving situations.
They do make a 10 rib direct drive setup to replace the 6 rib to jack shaft/cog system for those wanting to move to a larger Head unit (Paxton 2200R or YSI) but honestly I see NO reason why the current drive system couldn't max out (~14 psi) the current 1500SL thats being used and everything has held up so well really a very low maintenance/durable solution.
I'm at 550 rwhp/510 rwtq on ~7 psi with nothing done except the ECS kit but I am planning on adding meth soon to push the current 1500SL or step up to a bigger 2200R head unit (when ECS is ready to test that

).
This is a very well thought out kit and a great Value!
I urge you if you have any questions at all give ECS a call (Chris, Doug, or Alex those guys are awsome) they are great to work with and do what ever they can to help.
