need to know what the most average boost people got on a completely stock TT (auto if it makes a difference)

Im getting around .70-.72 bar... but before I was getting .8-.82 bar... consistantly

Please respond!

according to the manual a stock supra runs 11 psi which equates to .76 bar.

so if before I would consistantly hit .8 bar .. then after a plug swap Im now getting around .7 -.72 bar..

Was I running bad before and now running correctly, or is it the other way around?

Are they the same plugs you were using before? Thats only a little over 1psi difference. Weather could affect it that much. You could also have a small boost leak.

true ... I think Im more stuck on the number (bar) then the actual performance of car....

I had the original plugs in there.. and swaped with NGK 6097s with .40gap... would that make a difference to boost?

I have a stock (not many weeks more) TT auto...

I boost about 0,75 from that the second turbo kicks in until redline..

Maybe a little more about 0,78 when it's coold but that differens is so little in the boostgauge that it's hard to read.

If your car is stock why would you want to run colder plugs? Put a set of stock plugs back in at stock gap and you will remember why Toyota designed everything to work that way in the first place.
