just took my car out of storage for the winter and got on it and it chugged or burbled under full throtle...means to me i have to change plugs again i changed them at 10k with stage 3 and now with stage 4gt i think i changed them around 15 or 17 k or so ..i dont rmemember now i have 22300 on the car and its chugging whats up?
i HOPE its just the plugs....

 

It may be running too rich at part throttle.
