I put in a 76mm mass air flow kit and my car and now it is running like crap. idles like i have a cam , wot feels like a snail. sample tube has yellow paint on it so its is the right one for the 19lb injectors. small side of housing is faceing tb. the side of the sample tube with a slant is faceing air filter. put stock one back on car runs fine. and if the tube is made for 19lb injectors why is the tube so much bigger than the stock size tube. help!!!!!!!!!!

you might have to try clocking the sensor in housing some.

try rotating the meter around and see if that helps.

what do you mean clocking housing in some?

Well the tube size is supposed to be bigger since this is basically why you bought it..............its not the tube size that determines the injector size.

C and L has a calibration kit for each size injector you move up to.....The original unit should be for 19 lb injectors

B/c the mass air is larger, the sample tube is. It's all relevant

C and L has a great customer support as well. I had a few questions before I installed mine and they were precise and to the point......
