the addition of your vishnu up pipe probably aided in getting close to full boost in first gear. i have the vishnu up pipe, turbo xs turbo back with race pipe, turbo xs dual stage boost controller, aem cold air intake, 50hp nos wet kit. thats nos brand. and turbo xs stage 2 unichip. i acheive close to full boost in first gear also but i attribute this to the fact that i have no catalytic converters in the exhaust stream.
