it feels slower as it doesn’t rev up as quick but it can be a good thing. I’m making 600whp and 450tq on a mustang dyno around 32psi. So I’m glad it doesn’t spin up the tires and it doesn’t bang off the rev limiter instantly. I built it more for roll racing. Also since I don’t have to shift as much the car is just building and holding boost while other cars are shifting so it really depends on your power level and usage. Above 600hp the 4.11 and 4.08 are great in my experience. My car still hauls *** I don’t regret the 4.08.

I really like my 4.08 FD. Previous setup made 700whp ate up MPH fast, looking forward to see how it does with my new setup that will be making 850-900whp on E85 and will be running S3 cams.
