I have a 2.5 bar motorola and want to switch to a 2.5 omni bar....can i just switch and not retune or them both are not exchangable

 

help please FIgeek

 

i asked your tuner if someone doesnt respond. just to be safe.

 

They are very similar, but not exact. Depending on the software used, you may not see any difference. But to be clear, they are different.

 

i was tune on crome.....is there any difference....

 

It mostly has to do with the high vacuum area, specifically where the voltage cutoff is. It shouldn't make enough difference to be noticable, but it would be a good idea to check AFR's with a wideband. At most you'd just have to adjust the first two columns for idle.
