After having my wastegate fall apart on May 10th, I was able to rebuild it and get back on track for May 11th. there must still be an issue with the wastegate since spool was slower and peak boost was maxing out at 19psi instead of the 26psi I can normally run. 

Still had a good time, even with the lag coming out of corners and lower power I managed to match my previous best time of 1:52.8 on 225/45/15 CRS and with some old 205/50/15 hoosiers I got for free from a spec miata guy I managed to do a 1:51.29 

sub 50 is definitely within reach. 

Ambient temp 30C and sunny
