There is nothing inherently crappy about the C&L meters and they don't "trick the computer." The only meters that "trick" the computer are those that try to compensate for different size injectors without a tune. This includes C&L meters with optional sample tubes installed as well as Pro M meters and any other "programmable" meters.
So if you have stock injectors then the C&L is not trying to trick anything. However, it is just a plain fact that meters vary. I have tuned literally 100's of Ford cars of all types and have become quite resigned to the fact that essentially every non OE meter (including the expensive SCT meters) will need tuning from time to time.
Having said that, if you have a 76mm MAF and stock injectors then you should be using a yellow sample tube. If you have a 73mm MAF and stock injectors then the correct sample tube is clear, or no color. If this does not work for you then tuning will be required. I am going to say this here with great emphasis. If anyone chooses to ignore this warning so be it, but I am going to state some facts here, not opinion. If you choose to ignore this, so be it.
If you install an aftermarket meter of any kind and it seems to you that the EEC needs to relearn before the car runs correctly, YOU HAVE A PROBLEM. No learning should be required. If the engine doesn't want to idle then remove the aftermarket meter and reinstall the stock one until such time as you can have the car tuned. Improperly calibrated MAF's are the #1 cause of blown headgaskets and cracked pistons. Consider yourself warned.
But, you say, my car learned and then it was fine. Not exactly. Your car doesn't learn at full throttle where it matters most. Yes, eventually it will apply adaptive values to the full throttle datapoints but it won't happen overnight and there is no guarantee it will happen. Ever. And when it does (if it does) then you won't know when it did exactly. Personally I do not recommend taking such chances with a supercharged car all for less than 5rwhp.
"Less than 5rwhp you say?" Well, here is another happy little tidbit. If your car is nearly stock (less than 250rwhp), then you don't need an aftermarket meter. I have dyno proven that at 235rwhp the stock meter vs. 76mm C&L is no more than 3rwhp difference. You can't feel that and you certainly won't get even that much without tuning in the first place. Don't feel bad if you have stock injectors and you have to run the stock MAF. It will be fine.
