    I did a lot of reading on this. With the stock wheel you will not need a fpr with the reflash, but I would still invest in a AFR gauge. From what I saw, people were running in the low-mid 11s with the R3 and stock wheel-- a little rich.

    with the reflashes they tend to set them up a bit on the rich side to keep your engine safe.
    I recommend measuring AFR and using an adjustable fuel pressure regulator and then lowering fuel pressure to get the optimum AFR for max power
    Ideally you want 11.9 - 12.0 AFR although I have run as lean as 12.2
