The other night it got 12 degrees here and my heat exchanger coolant froze. I thought I had a 70/30 mix but I guess I fucked up and got the coolant to thin.

Fast forward to the next day and I get it thawed, drained and refilled with a 50/50 mix.

I head to work and do a short pull to build some head in the SC maybe 50% gas but couldnt stay in it due to traffic. I come to a straight stretch and go WOT in 2nd gear. I pulls hard till it climbs to about 5500 rpms and it just dies. It didnt stumble or stutter it just shut itself off.

I coast into a parking lot and trying to figure out wtf happend. AITs are 78,....no CELs. Look under the hood and everything looks fine but it wont start back up. Tried 3 times and nothing. After about 6 or 7 mins I try it again and it fires back up.

I get it to work and its running fine but idling rough and it has been doing the same ever since. Is there anyway you can loose your tune or it change if it misfires? My other issue is I my heat exchanger coolant isnt cooling my inlet temps. Pumps working and I have bleed all the air out. I can see it circulating in the filler neck but the coolant for some reason acts like its not passing under the supercharger or something.

I prolly have the slowest car here lol mods are 2.8/60s canned tune (ottp stg2) with ottp's big heat exchanger.

Please help lol
