Converter Tuning Issue???
Converter Tuning Issue??? 
I am currently experiencing some issues with my 3400 converter and I have been led to believe that it may be fixable by tuning. I have a base tune put on the car which is heads, cam, 3400 stall, exhaust.the first issue is that it seems to slip in and out of lockup while driving on the street pretty constantly....almost like it is fluttering.
the other issue that is more of the one i am worried about is that when the converter does lock up and you get out of the gas to coast....it lunges or bucks.
has anyone has these issues that knows how to resolve them with HP Tuners?

Your surging and bucking issue is related to fueling and spark.

the bucking issue isnt the RPM's or motor surging....it is more the trans or converter....is this still caused byt the fueling and spark issue?
