So, revert back to stock exhaust manifolds and now my af/r gauge miraculously works after 4 months of what I thought were af/r programming issues in the LC1 software. So, my current tune was done with that manifold and O2 sensor not doing the job.
Looks like I'm getting a new tune.....
Just installed my Grimmspeed thermostat a couple days ago and my car still got a little hot at the end of the track at RMR. Not really built for drag racing anyways, but how is that radiator doing for ya? I'm ready to upgrade mine.
