COLD WEATHER TUNING/RUNNING RICH-Help Needed

Greetings:


My car-89Turbo Engine was is modified-7006 Turbo-1bar-msd6al & coil-new injectors-ngk plugs.new accumulator-magnecor wires,Hks fuel enrichment,Air-box-mod k&n,SC Cams,B&B dual exhaust.Timing 26degrees/.040 spark plugs..etc.etc.


The car ran great in 65-80+ degree weather....

Now the weather is getting colder,40's+50+'s degrees the car is acting up.

1. Cold weather-Starting not a problem. 1shot. Holds rpm 950 constant. Perfect.
Boost comes in no problem. Short burts-30mph-60+mph- Feels good.

2. Now when nice driving/cruising-hwy 2500rpms top gear..No boost. The car does not like crusing. Wants to attack. The car feels slight BUCKING.

3. At Top End. Intermittent Bucking on Holding Boost 5th gear-Long Top end run. Feel slight bucking/not smooth throtle

I checked fuses, lines/parts etc.etc.Seem to be fine..Do you guys adjust your CO during the cold moths??Should I play with the mixture screw??? Could it be the WUR?? Possible vacuum leak???

Input/Suggestions Please
