I know lots of people that have dumped TT setups for a single turbo.

Several Supras come to mind first. They are always a ton faster... Imagine that.. Better efficiency = better power; every time...

I ran a 20G turbo on my Conquest (among others - 12A, 14G, 16G, T3/4) and never had boost lag problems. The only time it showed lag was below 2900rpm. I don't even cruise below 3k... laugh Exhaust setup can greatly reduce lag by itself (as shown by my Conquest's 3" single piping) and the newer turbos with VVT are even better!

Whoever coined the phrase; "If it ain't broke; don't fix it" ~ Just doesn't get it...
