If you are running a maf and boost, will switching to the cobolt SS 2 bar sensor mess things up or is it swap and go. In other words, do you have to alterr the tune at all to switch to a 2 bar sensor.

Sorry to highjack, but I figured this was better than another thread on the same topic.

 

Oh ya you have to alter the tune, you have to do a complete re-write. You have to decide whether or not you want to do open or closed loop then you fail MAF etc. etc. They be prepared to do some VE tuning on your new 2bar VE table.
