2 bar map sensor necessary?

[BoostedEX]

1 bar is 14.7 psi... So you'll be fine with your OEM one [img]smile.gif[/img]

I thought the OEM one can only read up to 11 psi, the 2 bar up to 14.5 psi and the 3 bar up to 29 psi?

anywayz, know where to get a 3 bar map sensor for a reasonable price?

I will be upping the boost in the coming weeks to the 3.8 pulley. I currently see 9-10psi on the boost guage. Supposedly the new pulley will raise boost up 2psi. That puts me at about 11-12psi on the boost gauge. Is that actually what my OEM map sensor is seeing or is it more likely only 8.5psi? I will be getting a retune in a couple weeks as well so I just want to be prepared. Do I need to purchase a GM 2 bar map sensor or will I be fine with the OEM map sensor? If I do need a GM 2 bar map sensor where can I get one cheap? Is there a certain part number I look for? Also where can I find a 3 bar map sensor? I need to pay back a friend but he just told me if I could get him a 3 bar map sensor, we'll call it even.

thanks

Chances are good that your stock MAP sensor is not really seeing 12 psi... and even if it did, it would probably be OK. Make sure the boost cut is unchecked in your Hondata rev limit tab... and you might do a datalog of a dyno pull and overlay it with your current tune map. This will verify if you are in fact reading above 11.3 psi at the sensor.
