I have a turbo EM1. Im running 9lbs of boost with a Hondata s300. If I just drop in some GSR cams will my car run fine without getting it tuned again.

it should be ok, but obviously not at full potential without a few alterations in the mapping.

right i understand that once I have it tuned for those cams Ill really see the performance gains. But im not gonna fuck up anything by just dropping them in? I need to break this down Barney style. Inline Pro put in adjustable cam gears when they did my motor swap. When I pull out my cams that I have right now, as long as I mark where everything is, when I put the new cams back in I should be good to go as far as timing?

It will not be ok. You can more than likely put them in and drive around without a problem, but dont get on it until you get tuned. Those cams will make more power and more than likely require more fuel and different timing maps.

Sorry, I ASSUMED that someone would know better than to swap shit out and then run the crap out of the car.

I should have known better.

makes sense. so I guess Ill probably just wait until I get all my head work done and take the car to get tuned again.

haha trust me you can never assume that with some people.

If you change something as major as your cams you will need to tune before romping on it. I wouldn't even suggest driving it down the street unless it is in limp mode (to keep the motor safe). All it would take is one surge.. pop.
