I just came from the dyno to check my A/F ratio and above 3500, I’m going to 10.9 and even 10.4 in places. For my MAF xfer function, I added 5% more fuel at the top to compensated for the 3.1 pulley but it seems like I don’t need to add the fuel and can just run the stock MAF xfer.
My tuner said to leave it alone. With this A/F ratio and 18 degrees of timing, I’m totally safe and it’s hard to find parts for these motors so don’t break it.
I’m thinking of running the stock MAF xfer function and 20 degrees. I think it’ll be safe and give me a little more powe.
What do you guys think? Mod list is real simple, 3.1 pulley, catted h pipe and Stinger Catback.
Thanks.
