CAI confuses ECU?

Hey all. I'm thinking about buying an Injen CAI. I've heard that changing the induction source can confuse the ECU because of the change in the volume of air being sucked in through the CAI causing problems in air/fuel ratio. Is this true or can you just swap it and there's no problem?

No matter how many times you reset the ECU, the Injen will always confuse the ECU. The reasoning behind this is MAF placement. Our ECU's are tuned to read MAF signals from a 2.5 inch pipe with special "fins". This is located on a straight section of pipe. The Injen locates its MAF on a bend with no fins. Thus, the A/F readings are normally off and thus, you have bogging on the low end. Only one Intake on the market has the correct MAF environment to allow correct readings...

TPR Intake! - Injens high end with AEM's low end and NO BOGGING!
TPR EXHAUST! - Exhaust made 10.5 whp peak and 32 whp at 6300 on my car!!!

I'm guessing that you're talking about TPR? I'm not sure they're available in Australia confused
