ifr is stock. looked at another tune for same year and i found that the eq ratio was different.

eq ratio gives you your afr WOT as long as the VE and MAF tables are correct as stated before.

should this be the same all the way across? or above a certain rpm?

some people will tell you to keep it linear others will tell you to taper it from rich to lean and vice versa. Typically it will be a linear 12.8-13.0.

if i put a number in trying to get 12.7 my wideband says 13.3ish. how do you make them the same?

You have to have the correct air also. Its not just dependent on fuel. You need to get the afr % error logged and get your VE table right.

The scanner is a vital part to tuning and is your friend.

You're definitely running too rich regardless of all the other info in this thread. You need to slow down a bit and take a step back. Read a bit and start working on getting your scanner setup for AFR % error and then get your VE dialed in. Next you'll need to work on your MAF. THEN you can start to tinker with PE and timing and whatever all else you'll need to get your AFR corrected on the juice.

Rest assured, you're leaving a TON of power on the table running that AFR on the spray. Take your time and get this right and you'll see what I mean!

you get them the same by tuning the injectors/ve / maf tables correctly. The PE enrichment add is based off 14.7:1 so if you're tables are off going into PE then your a/f will be off. Are you trims locking in at 0?

yes. is that right?
