No KR through out run, good, means also that your timing is fine. Long term fuel trims need to be brought closer to '0', max from '0' is usually 5+/-. Negative trims mean your running rich and pulling fuel. When going WOT neg fuel trims are dropped, meaning it quits pulling fuel (so it's not a concern at wot). If they are postive (adding fuel) they freeze and are added to your WOT PE multiplier. Now with that said, reading your narrow band 02's for a/f is a little hard. This is why, they are callibrated at 14.7 a/f and the farther you get from that a/f ratio the accuracy falls. So, to say that a/f is at 11.5 0r 12.1 on the spray is a little misleading using the NB 02's. This is why most guys use the wide band for tuning. I would guess from your 02 readings that your WOT a/f is fine, but you should check with a WB or get it on a dyno if you want an absolute answer. If you have a tuner program I can lead you through the process to get your LTFTs in order, and that'll better your part thorttle performance. Hope this helps a little.

It did indeed help. I was just mostly worried about KR which I knew I ddint have any but wanted someone that actually knew what it all meant take a look and make sure. I ran it with a 175 shot and it ran right around 12:1 on the nitrous so I upped it. After reading your response I think my tune is ok and just need to check my A/F with a wideband and make sure its ok. Thanks for the info!!
