I won't be able to 100%back up my claims regarding CnL until I get one on my car, but go to
www.cnlperformance.com and check out there 73mm MAF. Look at the dyno plots comparison between the CnL & ProM for the Mustang. There MAF really does work, alot of Mustangers use CnL. I'm in no way saying the ProM doesn't work, but I'm saying keep your options open there's another kid on the block and he wants a piece of the action as well
