Thats probably the default pulley combo for that motor from magnacharger. At that boost level, you'd keep magnachargers warranty. Keep in mind thats a stock vehicle with a 10.9:1 CR motor running 91 octane. This will be pushing the limits of a stock 4L70E anyway.

We have not done any back to back comparison on the same vehicle yet. The TVS1900 has alot more when considering what it made at only 5.5 psi of boost with a 3.3 pulley.
