You can get around this by using an AEM 3.5 BAR MAP sensor, but they are expensive compared to the Omni MAP sensor.
I doubt you're maxing out the stock fuel rails at that power level, but you're probably getting close, so it wouldn't be a bad idea to upgrade while you have it apart.
Buy the non-stainless AEM 3.5bar, they are much more affordable. like $65 i think.
