Im getting ready to retune @ 10lbs. The motor is a jdm b18c w/ 10.6:1 comp. I figure that will put me around 300whp, which is when the ringlands become compromised. Will lowering the comp w/ an inline pro headgasket allow more power because of less pressure. Or is 300whp , 300whp reguardless of compression. Thanks.

 

lowering your compression with that gasket throws off your cam timing and decreases power of the engine unless your raise boost to compensate. It does allow you to run more b00st "safer".
