Ask steve @ sst. I wont be going down the drags till I have the wolf3d in and tuned. Dont see the point in going until the car's setup right, plus my tyres are hitting about 12 months in age, although not completely lacking in tread I'm sure they wont be as good as new ones but I'll still give them a try. I think my stock ecu is ****ed, in the mornings (cold or not) the car searches up and down, sometimes to the point of stalling but doesnt quite and then finally settles on about 1500rpm till it warms up and then sits around 650rpm, sometimes the car idle is lumpy too, but I think thats spark plug related.
