[QUOTE="Chonger, post: 864087, member: 11123"] I think the most common problem you will see with the predator tune is that it tends to run a little lean in the midrange and rich up to. I would like to lean out my AF chart a small bit after 4500 RPM's but can't without a custom tune because the midrange 2500-4000 is at 13:1 and I don't want any part of the AF going any leaner than that. The AF adjustments do not do me any good here because I can only make adjustments across the entire RPM range. Don't get me wrong. I am glad I purchased the predator because I did get some good numbers from it and there are many other options on it that are useful. However, if you are looking for a totally flat AF line your are not going to get it w/out a custom tune. Also, every tune seems to give different results. I have seen 2 cars with the exact same mods be tuned with the predator have 2 totally different AF ratios. [/QUOTE]
