it doesnt matter if the transmission is auto or manual. it tricks the ECU to not throw a CEL when your running rich on stock injectors on a greddy turbo kit.
yeah it doesnt matter if its auto or manual
also its not just for a greddy turbo kit cause greddy doesnt make one for the 7thgen
it doesnt even have to be used for a turbo at all i was gonna use it to tune my cam
