I just had a fuel pump, injectors, and a SAFC installed on my car. We got the low throttle settings tuned no problem. The car idles and drives fine, but so far, WOT tuning has been hell. For some reason it wants to buck hard under acceleration. I started with high throttle settings all zeroed so I thought it might just be loading up on fuel from the 660's. Didn't seem to be the case. Do you have any idea what is going on?
