HUh? What do you mean the 3-4 shift is only 800-900 rpm drop? I have an MR, and when I shift from 3rd at ~7100, I end up at ~5600 in 4th.

 

ok dont believe me... my gauges isnt off because my blitz timer was reading the exact same thing as the autometer.. It's called DRIVING and a sticky track....

 

It's likely the blitz timer is off, too. Neither of those can be expected to be exact. Also, driving and a sticky track don't create your trap speeds - just your ET. The point of contention is you trapping that speed on such low boost, but IMO, it's just that we all refer to boost in different ways. If you saw 20psi in 4th after your shift, which means you were close to 6k rpm, that means you were running 22-23psi in actuality, because we refer to boost as the peak boost you would see from a low rpm roll, not after 2000rpm of taper.

 

wow, your car is a freak, I don't care how well you drive. Your ix is as strong as my 8 on race gas with cams running 25lbs of boost.
