This is why I personally am against mail order tunes, unless you data log and go back and fourth with a tuner and have the ability to verify air fuel your blind. If you notice this car came in with a mail order tune, however take notice how lean the car was. We tuned to the leanest bank. Combo is steg port, 2.6 pulley, CAI, innovative 10% underdrive pulley and long tubes. This is another reason why we do not believe in dirty tail pipe sniffers, we use DUEL widebands with fresh sensors. You will see the first graph in black was post cat which yields .5 leaner readings we also had a 3rd wide-band pre cat feed into the lifelink software which yielded a 12.6-12.7. Mail tune had 20deg of timing in it and AF was 12.7 we made the same power with AF 11.6-11.7 and we were more conservative with timing.
