Some problems getting worse

[97 Talon Kid]

Ok, i'll just go threw some problems i've been noticing

at WOT my car will smoke not sure of the color i always catch it in my rear view mirror

from a roll at 45 WOT to 50 i hit full boost yet feel the car boost on and off i guess like a very slight jerking no one else seems to notice it but i feel it also it takes like 5 or more seconds from 45 at WOT to reach 50 anyone have any idea on what's up?
(I personaly think bad gas f&^$ing speedway )

So, if anyone has any idae throw it my way thanks!

1. Boost leak test. How to make one and use one. Post results of that when completed.

2. Compression test. How to do a compression test. Do a dry one first, then a wet one if any of the numbers are extremely low or if there is a difference of more than 13 between cylinders. Report results of that test.

3. Check turbo for shaft play, just in case the smoke is whitish/gray and your turbo seals/bearings are failing. You can do this at the same time you do the boost leak test and it'll take you all of 30 seconds longer. Pull off the intake pipe, reach into the turbo inlet, try to wiggle the compressor wheel; up/down, side/side, in/out. If there's play in any of these directions, especially in and out, the turbo may be failing. As an extra precaution, you can check your lower intercooler pipe for pools of oil.

4. When was the last time you replaced the spark plugs? Were they NGK BPR6ES's? Were they gapped to .028"? What do they currently look like?
