Acceleration question.

[derekajones]

Hello everyone,

I am having a bit of an issue with my 87 gn. when I start to accelerate the car bogs right out at around 5psi of boost and it sputters.. there is no black smoke out of the back when this happens and when I let off the gas it drives just like normal. new plugs, new maf, new air filter and brand new turbo. any help would be very appreciated.

Thanks.
