Tunning question

[Gravy]

I think tonight i'm gonna set the MAF translator to -20% across the board, i'm running around -15% to about -18% so i'll be able to run closer to 0 on the safc, but i'm pretty sure that's still gona give me the same results as setting the safc to -20.

And the reason i went with the 450's is i had to run e-85 on the 550's to prevent running around -30 to -40 to keep the AFR correct. I've almost wondered if they are larger than 550cc's but a run of the part number confirmed it twice now.
