93 Octane

Engine feels smooth. Good torque down low, pretty linear power up until shift.

3 logs. 1st is normal driving 2nd is pull 3rd is normal driving after pull. Through cylinder 4 and 5 misfires after pull

Recently changed the exhaust to a straight pipe setup. I noticed I'm targeting 20psi of boost but it looks like we're only consistently hitting about 17-18. Any ideas as to why? Maybe a boost leak ? It also says that I'm only using 80% throttle however I did have my foot down all the way. Otherwise, car feels pretty good. Pretty smooth, pretty quick. At the top of 4th gear we were going about 140mph.

Mac disconnected. Wastegate pressure only
