I bought a 2009 Gen 2 busa it came with stock pipes and PC5, It back fires in 1st gear if i go to 5.5rpm on deceleration. I'm wondering if it was tuned wrong. Also, If I disconnect the PC5 will it revert back to original stock MAP? I want to test and see if the back firing would stop if I disconnect the PC5..Any suggestions?
