Help! Overboosting...
i just installed my hallman boostcontroler last night and i switched to the heavy spring and with the boost controller as low as it would go im hitting 25+ pounds of boost.... i didnt hold it, i just notices it when iwas trying to hit stock boost. i put the light spring in and it did the same thing.. i have the vacume line coming off the wastegate to the 90 degree nipple on the MBC and the vacume line from the BOV to the other nipple on the MBC. theres no leaks anywhere. and i know my boost gauge is accurate...
Any help and/or insite to why its doing this?
