I think the tiny lag STS setup can occur, if there is one (I don't think it will be an issue because more the turbine will run faster more it will accelrate quicker), compare to the simplicity it gives...wins hands down for low boost application.
David Smith - ESPN Russell Racing School, Driver at the 2005 SEMA Show
"The STS Turbocharged Corvette Z06 exhibited no lag or anticipation, and had a super linear power curve. I'd vote it an 11 on a fun level of 1-10! The sound was absolutely unbelievable, I've never heard a street car that sounded so good!"
Patrick McCarthy, instructor at ESPN's Russel Racing School
(Patrick is a professional driver that drove the vehicles at the 2004 SEMA Proving Grounds)
"These turbo systems spooled quicker than any other turbo I've ever driven. The power comes on smooth and is very controllable, giving a great throttle response."
Evan Griffey - Editor of Turbo and High Tech Peformance Magazine
(Evan's 3 page article on STS appears in the October 2004 issue of the magazine)
"The velocity of exhaust gas and the fact that the STS design features a good deal of straight pipe, coupled with what exhaust gas does when it enters a turbo, should help negate any "lag" in the system."
Joe Pettit - Editor of Sport Truck Magazine
(Joe recently installed our system on a Chevy 4.8L Silverado - details are in the October 2004 issue of Sport Truck magazine.)
"When we first saw this turbo system at last year's SEMA Show, we were very skeptical about throttle response. We thought that with the turbo so far away from the combustion chamber, the system would be lazy with a lot of turbo lag. But after driving the system on other trucks as well as on this install, we find the lag not excessive in the least; it is very near what you find on factory turbo systems."
Kenny Duttweiler - Duttweiler Performance, Inc.
(Longtime "Turbo God" Kenny Duttweiler has a well-established reputation as the finest turbo tuner in all of drag racing.)
"Squires Turbo Systems' remote-mounted turbos have solved all of the problems associated with traditional engine-mounted turbo systems. The intense underhood heat a turbo generates has been eliminated and you no longer need to punch a hole in your oil pan or cut up the front of the vehicle for an intercooler. Emissions should be really good too with mounting the turbocharger after the catalytic converter."

google "sts turbo" and you'll see some youtube video popping up.
I'll try to find the most info I can and share it with you.
