mines pretty laggy off the get, wish i woulda kept my stock turbo and made a poorboy twin setup. after 1400-1500rpm its a pretty good kick in the pants as it spools up. im too cheap to replace the 35psi boost gauge, but near as i can guess im hitting close to 50psi with the box on 5x5. towing can be a p. i. t. a. allways watching the pyro ready to downshift... .
"I ASSume you intend to use this in a twins setup? If you're proposing to use a B2 as a single, then you might not get ANY boost from it!"
B2 is a killer single turbo in the right applications... .
