Got an rx7 with an LS1 from an 04 gto. I did some data logs on hp tuners and noticed sometimes at high rpm the MAF air flow but not hertz will go 0-500 back and forth badly. And it seems to directly effect the injector flow rate and duty cycle. Sometimes spiking duty cycle to as high as 115%. It is basically a stock engine with long tube headers and an intake. Still has the oval MAF sensor. I was about to install a card type MAF and ls3 corvette intake. Any ideas?
