I know decking a N/A block for near zero or zero deck height does everything good for compression and to ward off detonation due to the better quench area. If you did this to the turbo engine, yes the compression will increase maybe a point and a half or a bit more from the stock 7.8 to 1, The throttle responce will be crisper, BUT will the engine tolerate the same amount of boost WITHOUT encountering detonation due to the tighter quench area Mark
