Need input on set up!

[GTP4]

I would recomend 103's with anything below a 3.4....3.4 and above I would use 104's.

So stick with the 103's on the 3.2",then?

I have a difference in opinion here with the spark plugs hehe I personally wouldn't want to see a 103 on any 3800 making less than 300hp. 104's are just fine, 103 is just way to cold. You need that heat for so many reasons. I don't care about gas mileage but 103's would make you get worse. With my setup i only run the 103's when i'm spraying and change them out to 104's for daily driving and no spray runs. I'm maybe 270ish off the juice and ????? on it.

Tq management settings in my car are all disabled, just thought i'd throw that out there. BUT keep in mind i have a tranny man trans. It's pretty built, but i did have them disabled with my stock trans too... Which is probably why it's sitting at Sinister Drag Design instead of in my car. It was shifting fine, but slipped soooo bad when i got on it. That was the end of that haha.

103's would result in worse or poor gas mileage?
104's would hep me in getting rid of some of that kr?

103's will help get rid of more kr they are a pretty cold plug. You want the hottest strongest flame possible in the cylinder, so when you use the 103's they're to cold. I would use the 104's for that setup, maybe if you made over 300whp i would use 103's but you shouldn't have to go through that much to get rid of the knock you're having. Not to many enthusiasts care to much about gas mileage, which is a good thing lol, i know i sure the hell don't. I get like 15mpg's on a good tank of city, and 20ish on a good tank of highway. For e85 that's not bad IMO. I guess it really doesn't matter what plugs you run, maybe stick with the 103's because of the knock you can't seem to get rid of.

This is what my buddy posted on other forum, to try to help me:

Closed loop desired A/f 14.7.I will check the base Pe when I get home. The tune started as a DHP 1.0. Then we added the 85mm maf bin and ran the table mod to get the LTFT's to 0 at idle, cruise, and WOT. Then Tony added the xp cam and we retuned and raised the shift points . It is going to be hard to get a perfect tune without a WB. ""If anyone has a PT that would like to look over the bin file just let me know and I can email it to you""

Thanks
