so you got a 25% torque increase from a set of headders? (compared to the stock manifolds, right?) yes,you leaned it out a bit and added a bit of timing, but i would not have thought this possible. stock cam and everything, right?

moffpipes

I haven’t touched the VE table at all, just a couple of degrees in the ethanol adder table. Should have specified, but both runs are on e85

edit- I wouldn’t have thought I would see anywhere near this level of improvement, and this could be attributed to having high flow cats installed as well with the new pipes, but still, it’s a massive increase for bolt ons and an unopened tired motor.
