My M62 E85 car will wax the floor vs most TVS cars on gasoline...

of course you could. but it will still ramp the boost (although much quicker) instead of making BAM! 16psi like the m62.
most poeple that have gotten the tvs (myself included) have only been on the stock pulley. i watch the boost gauge make 15, 16, 17, all the way up to redline where it makes 20. when the only other difference was the m62 w/2.8" pulley, you punch the gas at pretty much any rpm and ~16ish psi was instant

There seems to be some confusion on the TVS making less boost than the M62 down low. I think it's better worded that the TVS makes MORE boost up top, not less down low.
With a 2.8" pulley on the M62 and a 3.15" on the TVS, I believe the M62 is effectively a larger blower which would explain the surge. Not to mention, cars with top end power feel like they have less low end.

They seem to be on par until ~3200 rpm.

My point is, John's statement is incorrect. The wheelspin should still be clearly evident as the dyno graph he posted shows the TVS and M62 making IDENTICAL power down low. This istant grunt that would normally not be felt on the TVS, is clearly shown that EB's car still feels exactly the same as his M62 did, only with better top end.

that makes complete sense, and that's true to what I've seen on MOST dyno's. But the dyno graph that EB posted, shows IDENTICAL hp and tq numbers down low between the TVS and M62, which would mean the car would feel the EXACT SAME, yet the TVS has quite a bit better top end, meaning the car would pull away faster and faster as you climb higher into the rpms.

how would you know? You never drove a tvs car. and we are not talking about curves, although if you look from 1000 to 2500 its clear even on Erics chart. Tennpenn is correct. and Zoomer. The car does not feel the same TVS to M62, just like these folks are saying (who have TVS) but in the end who cares, you dont have a TVS. meh why bother

I was thinking more about the Tq/hp differences or similarities in the low end.
I have sputs 2.7" E85 dyno runs but car made quite a bit lower tq then mine. His timing table is a lot different then mine.
I would think that with a smaller pulley the Tq/hp differences would become more obvious sooner in the RPMs.
