Cheap things don't go so well 90% of the time. No proper ECU limits tuning + Somewhere if you push it to 250-300whp mark + non-conservative tune = Broken ringlands, shot a rod, melted piston, lifted head etc....

Apparently its runnig standard compression. Unsure about leak down an comp test. Was never given the dyno sheets but was there the 3rd time it was dyno'd. Probably get a retune early next year.
