Im running ngktr6 for my nitrous motor and with the plugs at .038, the cars runs a lot richer than before with the stock gap in it. Can this be changed with tuning? It loads up a little hear and there and the smell of fuel is greater than before. Ive gone back and forth with plugs for the last year or so. With the stock gap, it ildes perfect and runds great. With the tr6 at .038 it idles lower and so on... any info would be great.

 

You do your own tuning?? If its mail ordered, its tuned rich on purpous. When I saw my file from PCMforless, there was ALOT of adjustment ontop of the PE tables. I took it out and cleard right up. I have TR-6's with .035 gap.

 

PCMforless did do the tuning and it was great for a stock gap on the plug. So i will have to get it redone by him or just get it dyno tuned. Glad to hear its a issue that can be fixed by tuning. Thanks for the info.

 

i'll have to look at my tuner cats but ill find the part where it can be tuned down. Bryan had waaaaaaaaay to much over above the PE table.

I had my car dyno tuned with a wideband o2 sensor, to verify this.

 

The car dynoed on a wideband as well and was 11.2-11.5 a/f the entire range and was just pooring fuel out. I will have to get it retuned. If you have a tune or info on your pe tables, that would be great. Thanks agian.
