I'm running a VF34 with a TXS Topmount
I'm tuned for 18psi on 93.
In the colder temps my boost would climb to ~20psi.
Running map1 on 94 in the cold almost feels like running my race gas map5 in the hot weather on C16.
I haven't changed any settings on my tune other than moving the MAP value from 7 to 10. How do I determine MBT?
