Hi guys, really need some advice or opinions. I don't even feel the big push anymore. I don't know the 1st one don't kicks in or the 2nd one. When I drive up to 4000 rpm, I hear the intake sound is sucking air but I can't feel the push but I can hear the engine is sucking air if I keep pushing gas. I can't feel the little push on the 1st turbo too. It just like a NA car now. There's no white smoke, everything is fine. I took it more then 5 mechanic shop to check. But no one can tell me the exact reason is. They said is may be the turbo. And tell me to change a new one. I need some advice. Just don't know what to do now, where to check. I am located in So Cal area. If anyone live around my area and have a good mechanic shop for me to go check, let me know. Help!! It's so slow now, even a integra can keep up with me so close. Please give me some opinions or if you guys know every well on this car and live close to my area and hope you guys can take a look of it. Thanks a lot..!!
