you need to start off getting your longterm fuel trim values as close to zero as possible, you can do this two different ways:

tuning with ve tables
tuning with ifr rates

Since you are somewhat new I would reccomend tuning with the ifr rates, while you are scanning look at your fuel trims & drive under as many different load conditions as possible, no wot yet. then depending on whether you positive or negative tune accordingly.

if you are say lean (show +8%) I would decrease my ifr rate across the table say 4% (so you would type in 96%). then retest until you get between 0 - -2%. once you have done this you can start doing some wot passes scanning your o2 sensors or using a wideband on a dyno. If you have access to a wideband I would shoot for 12.8 - 13.2 afr. every vehicle is different. I try & start out with about 12.7 & end up with 13.0 on the big end. I make the smoothest flatest curves with that. are you can shoot for about 950mvs. this is not very accurate though. you can adjust this by using your pe vs rpm table. if your lean multiply by certain percentage & retest.

as for timing you could email me your file and I could show you some pretty nice, smooth curves. I found that my truck runs best with 34 degrees total advance, unless I am spraying.

Unfortunately, that's what can happen with over-camming a motor for it's intended useage... When this happens, a lot of people with throw a higher-stall converter at it. It'll help around town, but not when you go on the highway or your converter clutch locks up in overdrive.

Tuning is very VERY involved. Basically, the computer will do it's best to learn everything between idle and WOT. It will learn some idle, but not all. It will not learn anything at WOT. It will learn all fueling in between.

Idle stuff - you'll have to check with the guys on here - I only have experience with drive by wire TB's, which are different from yours.

WOT - you'll need your LTFT's down below 0, and you'll need a wideband.

The doggyness around town - I hate to say it, but you'll be hard pressed to sort much of that out with tuning. Your best bet is to look into SD tuning. I don't mean to be "that guy" but you'll really need to run some searches for info on that. It's a pretty involved process and I'm sure to miss details if I try to give a 'how to'.

Sorry I'm Mr. Doom and Gloom here... I know just how you feel. I had a cam in here that was too big for me and my mods.

if you get it tuned propery by someone who knows what they are doing, you should have no problems.
