    I had the same issue and my tuner suggested doing the rear boost solenoid and vaccum box delete and worked perfectly for me! Something about crap being built up in the box or the box starting to detierate. Also you can replace them but his way is free and gives full boost in 1st and 2nd gears too

    Do you have some sort of diagram on how to do that. Mines still got the boost problem as well.
