No, not the same boost level, both tunes are done to achieve the highest possible power on 91 octane pump fuel. The boost pressure that made the highest power level on the TVS2300 was about 7.2 psi. With the TVS2650 we are able to run about 8.5 psi and still hold close to 20 degrees of timing - which is the magic point on these engines.
If you're below about 16 degrees you're running too much boost, you'll make more power by lowering boost and increasing timing and vice versa, if you're getting up to 22 degrees, and you have enough fuel, power is yours by adding boost and lowering timing. While there's a bit more to it than just that to make big power on these DI engines, that's a good rule of  |
I was going to ask the same question then see this answer, Great Job Mike.
Looking forward to the differences we see from the LT4 Blower to this one.
