Im not sure on n/a timing & will ck on jets. Everything was adjusted when it was on the dyno & its been awhile so i dont remember. I had the motor tuned with tr6's in it but when i go to a br7 or br8 it wants to load up a little seems like. Would the n/a tune be that different with a colder plug? Another ? is i can run a tr6 plug & car will run around 7.05-7.15 on motor. Put a br7 in & the best i can get is 7.35-7.50. Would like to run br8's all the time so should i get the tune redone just for that plug?? Thank's

Those plugs are useless for nitrous tuning as others said.
It also looks PIG rich at idle and cruising.
Lean it up at idle and cruising until it's in the 14.2-15.0 area to help keep the colder plugs clean. I am able to drive on B8EFS just fine on pump unleaded, but with leaded fuels it doesn't matter how lean it is it will still load up after a while.
At idle every car will want a different afr value as different cams pull different amounts of vacuum and if you lean it out too much it will get what is called "run on" where the cam never drops back into a lope. It takes a good ear to find that sweet spot where you cam wants to idle at, but leaning it out will help keep them cleaner.

I need to get a wideband so i can watch it closer but im just not crazy about it reading it on one bank. I just started working on it again. Im prolly going back in a week or so to my tuner so he can adjust on it. I know alot of u r really good about reading plugs & geting the tune dead on so i was just wanting some opinions on it. Hopefully i can lean it out some & get some power out it. Thank's

If you plan to keep the 8s in there anyway, tune the car for 8s, then adjust the nitrous jetting for nitrous fueling.
