Well I found the main contributor to my original 1.8 letting go. The hiccup that plagued my original motor still existed after swapping the new motor and occurred with either 1.8 HPFP. The last time my car ran well was at Pocono in 2018. When you run the North Course at Pocono you are in a long right hander for almost half the track. One of the sessions my fuel level dipped below 1/2 tank which starved the LPFP of fuel long enough to damage it. The damaged LPFP caused a lean mixture at high RPMs.
Yesterday I installed an APR HPFP and LPFP, and the problem was totally gone! Pulled like a freight train all the way to 7500rpm in first through fourth. Case closed. Man this car is fun, I can't wait to get a little more seat time! A proper dyno tune and it'll be a freaking rocket.
No issues running upgraded pumps? Also 7500? I run apris38 and cant get more than 7200rpm.
