Over the weekend I went up to Shaun's in J'ville. We swapped out my TB with the one he optimized and opened the secondaries on my SVT a bit.
Overall I love having the secondaries cracked. There seems to be more power at the low end and a little more responsive up to 3400 (could be TB). However, I've developed an interesting case of throttle hang.
At any speed when I push in the clutch the RPM's will only drop to 1500-2000. Only after I've come to a complete stop for 15-20 seconds do the RPM's drop all the way back down to 750-1000. I don't have any sort of TH fix installed and the computer should be used to the change by now.
Any thoughts?
