I took a week alone of dyno testing just watching timing, checking pinging... etc... the car took alot of abuse but the only way to truley know if somethign is right is to test it... and the cars ran the same... normal timing for 91 is around 18 degrees.... sometimes 20 if you get a good batch.... then on 104 gt plus it will just stick at 30 and hold.... it's beautiful.... and with the pistons... it was exactly the same... car was happy as stock... except there was one time where a car had some bad gas... lol... I have seen it pull till 6 degrees... very impressive that the mini has that kinda resolution....
