car made 673/742 on a tr6... on the bottle.. 484/462 on motor.. so do i need to re tune it with the 7s in it or what?

imo a 6 is too hot for that much power. i run an 8 in mine. ive actually had my 8's in since february. 2 track trips and over 3k street miles. no problems. although i think they are due for a change. i tuned my car with a 7 in it and never retuned it with the 8's. i cant imagine the tune is that much of an issue. may want to look around. did they all foul out?

oh yea... missfiring the whole way home only sprayed like mabye a bottle through them and that was like a month before... but was making a pass on motor.... on the street and just started missing like crazy.... put 6's in it and runs like a champ..... i also lost 2 tenths on the 7's.. so think i could toss more fuel/timing back into it or gap them lower?

sounds like there might be too much fuel in it now. imo there is no reason it should have fouled them like that. i always put them in at whatever gap they come with. i just check them and make sure they are all the same.

i belive what ur saying... and on my wide band it reads like 12.3 at wot.... n/a dont know what it does on the bottle yet.. just installed the gauge...i can tell u this though the tr6's looked perfect when they were pulled out.. no issues at all with them

I run TR7s all the time, on motor and bottle. Now when I switched to the 7s, it is a little cranky on the cold starts but once it's up to temp it is fine.

your too rich on motor...i doubt you "fouled" them out...i run 7 in my car that made 355 hp for over 2 years and never removed them...

post pics...most people cant read a plug...

if anything you might need to open the gap on them some...if not its the tune...switching plugs changed cylinder temps and changes the tune...need it tuned like your goana drive it/run it...


im still confused why supra guys "foul" plugs and have to change them e very few runs???

You're probably too rich n/a, get the n/a a/f strait and it will be fine, gap them at 35.

The nitrous tune should have the fuel added it needs to be right, not a rich n/a tune that's getting leaned out from the nitrous.

I run 7's all the time NA and have 0 issues. There is an issue with the car or tune if you are fouling the plugs.

Dont change anything in the WOT tune .... just lean the idle cells out. ours idles at 15:1 with a **** load of timing in it to keep the TR-11's clean as possible.

ya liek the others said you wot is fine. its the cruise and idle thats likely screwing them up. you dont drive around town at wot.

I run 7's n/a and 8-9's on spray. Never had a problem with the 7's n/a. Like the above said, you need to lean it out at idle and part throttle. I idle mine in the 15-16.1 range.
