Hello guys well basically I'm running a 2.0 zvh with decompression plate however I want to up the boost and get more power , however I've heard keeping the keeping the plate wouldn't be a good idea at high boost , is there another way round it without doing the exspensive route ie boring it out and sticking c20let pistons?? in thank you Micky

I'm a bit new to this sorry if sound dumb but would Mahle oversize pistons and rods get rid of the decompression plate and wod the engine need boring out to fit these ?? Thank you Micky
