i Just got my grand national not sure what turbo is in it but its an upgraded turbo with the stock chip everything else is stock. i'm having a problem where it feels like i loose power once i get to 8 lbs of boost ( on the stock gauge) like you get thrown back in the seat then it seems to just like levels off in power it seems to hit a dead spot in the power band. i guess thats about as best i as i can describe it wondering what the problem is.
