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.

I guess I have a normal 94 TT with the average boost / vacuum leaks... but normal power.. correct?

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.
