Big News!!! Whipple is now supporting Long Tube Headers for non emission states The tune is done, works great, all the safety settings are still intact, closed loop is still on, a new model was built for the predictive system based on the SW LT's and other changes and updates. Whipple will update any current Complete Whipple kit (free within 1 year of purchase of kit) that has any issues. Anyone who purchases new, must state that they have LT, anybody that purchased for stock, and later added LT's, needs to pay for an update. This is Whipple's thread, but I ask if I could post this for now.
