Hey guys got a question for ya. Currently I am running a 9psi spring in my wastegate. At WOT my gauge reads right at 9-10 psi, but in my datalogging my Map sensor is showing 17.7-18.2psi on my Fast bank to bank. I am just wondering if there is a formula that makes these two even or if there is a table I need to make changes to in order for the Map sensor to match the boost gauge. The map sensor is one from a 87 grand national 3.8l... Thanks!
