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...
