So I think there would be just a bit more gain from a stock radix kit on a LQ9 compared to an LQ4.

So at this level of power, there woud be no benefit of the LQ4s lower compression level.

The gains should be the same 100-120 rwhp. He is about 20-25 hp off. I think there is a combination of things going on here, something in the set up. I hate the flowmaster exhaust, it is not good for FI at all.
