I'd be interested to determine whether or not my using a DOHC ecu had any bearing on performance of my SOHC engine? I remember reading something on the Cobb Tuning website that the MAF based ecu's can compensate for variations in environmental conditions better than MAP based ecu's due to more accurate fuel mapping. That being said, I have noticed that the SOHC engine in my GT seems to pull fairly strong all the way to the 6500rpm redline. I'm not sure if this is due to the MAF ecu or any other additions made to the car . . . I just have an intake and exhaust . . . nothing major.
Also, I noticed that you compared your GT to an RS . . . are there more driveline losses associated with a larger driveshaft, or are the differences negligible.
I'm not trying to poke holes in your comparison (I'm saving it on my computer as we speak
), I just wanna know if I made the right decision in swapping out engines . . .
