When l have it floored or am just speeding up l can feel the turbo kick in then about half way through it it feels like it sputters or looses boos for a second or 2. What is causing it and how might l fix it?

if you have an aftermarket turbo then you might need to get a turbo timer asnd a boost controller.and if you dont,check your oil hose(from engine to turbo)and make sure all your filters are clean..and l would recomend you to gwt a turbo timer and boost controller anyways.hope this helps

are u shifting grears or is it automatic cause if it is shifting gears the turbo is gonna cut out when it shifts the gears so the car wont build up on the boost

are you stock? if so check ur hoses there might be a leak. if you have some mods you may need to be tuned. At some point ur engine may be runnin lean or rich with can cause a misfire.

l had the same problem. It was caused by the fuel cut off valve. l swithched things around and upgraded and it got better.till l got an exhaust leak. Then it started doing it again.

Ignore the suggestions of the boost controller/ turbo timer both are a waste of money. Moving on l would check for vacuum leaks and exhaust leaks. Have you tried adjusting your wastegate arm? Any mods?
