Here's the sheet from my latest dyno. The background:
Last time I dyno'd...no A/F readings...211whp @19psi. This time, got rid of the cat, and switched from stock (4G61T) MAF, to a 2nd gen DSM one. Even with my SAFC maxed out, my 450cc injectors, meth ijection, and dsm smic weren't enough to prevent timing from being pulled. BUT, I still made 213whp at only 15psi of boost. So next step is to get bigger injectors (probably 650ccs), a walbro 255, and probably a SAFC2. But by then I'll be doing a whole shitload of other mods, so it'll be a totally different monster. In the meantime, I have the boost turned down to keep it safe.
Check out these ridiculous A/F ratios:

BTW...this is in the 1989 Mitsu Mirage Turbo, one of only 1500 ever made. Completely stock 4G61T block. 14B turbo, 3" turbo back. About 2500lbs with me in it. Well, maybe 2550 ;)
