Yes the C&L is a drop in unit, you just transfer the Hitach Hot Wire Sensor on top of your stocker to the new unit, like previously mentioned, you tell whoever you order it from what injectors you have and they will send the right sample tube along with the new unit, it is usually installed upon delivery.
I had this same meter and it worked well, but there IS an advantage with the other units that are flowed, not so much a PERFORMANCE advantage, but a unit such as a Pro-M , the sensor and unit are put on a flow bench and matched perfectly, this helps DRIVEABILITY big time now and in the future as your package progresses.
I also commend you on your choice of 30 pound injectors rather than 24's, 24's barely outperform stock 19's and the 30's allow you to build on them with good driveability, BUT, like I said you don't need 'em now, but when you do upgrade, go with the 30's.
By the way, did you guy's know that Bob Atwood, Owner and President of Pro-M died, I have talked to him on several occasions, he was a true pioneer in our sport.
Good luck!
