past couple months i have had problems with under decent acceleration the car would accelerate fine then act like fuel cut sounds like a 2-step almost. my boost gauge i installed is reading around 15psi that's not spiking is it??? i changed my plugs new air filter and changed the oil hoping maybe something would change it to no avail it still does. just yesterday i had to get on it and used WOT it acted like 2-step again and fell on its face lost all power idled very weird as if only running on 3 cylinders shut car off runs fine but still spits at me. i am at a complete loss can anyone help!! thanks in advance.
