I've been running them this year also. I've found they are happiest around 28psi all around on my car. I've always sprayed between runs except for yesterday. My fastest run was my last run where I dropped a complete second from my time(also 2nd fastest overall ) so I may try them with a little more heat in them at the next event, but at the same psi
