My car has an hks smf intake, a stock elbow to 3" DP to Titan 3" cat to 3" RS-R catback. She has about 140,000 miles on her. My question is that she boosts to 9-10 psi in the summer months and 12-FC in the colder months. With these mods is this normal? Or is my wastegate not working properly?
If the wastegate isn't working right could I replace it and add a boost controller to regulate a just under Fuel cut psi constantly.
