Hello all. Recently building this motor from my old one, and I have raised the compression to 11:5:1, have ported block and heads, and .020 over (96mm) bore. Since you have to break in the engine for the first 500-1000 miles, would tuning it after be fine and could the ECU handle the changes of internals without a tune? I know the dyno really stresses the car out, and I was just wondering if it’d be safer to break it in first.
TLDR: With a raised compression of 11:5:1 and 96mm bore, can the ECU still drive and run the car without damaging the engine till it breaks in and can go on the dyno to be tuned? Thanks !
