Well most people have no way to find the difference between locked and unlocked at WOT/full boost because the computer wont let you do WOT in lockup. You have to be running a switch to find that number.
I dont see any issue with the gearing thing.. If you dont want to go past 5500rpm on 225/50/15 on 3.02fd trans that all adds up to me.. youd want to get out of it somewhere around 120. Doesnt mean you HAVE to but nobody likes to run a motor out of its comfort zone for long periods. When im going 100+ in my DD neon i shift 'early' into 5th just because i dont like hanging out at 6k+ so long to actually 'gear out' in 4th. It's just unnerving and pointless.
