hai AL...............if i change the bov from MR bov to aps bov after custom tune, it's that gona make any different or need reflash?

 

Im not AL, but ther should be no need for a reflash if the BOV is recirculating....

 

i took the the GFB out and put the stocker back in and i was running crazy lean afterwards.. this was after running the GFB at full recirculate. I wouldnt risk it.

 

was that with Dynoflash?

 

I don't see how it's possible to affect the a/f ratio with any BOV's as long as they are recirculated 100%.

 

thats what I was thinking

 

This is from page 4 of the chicago trip, from the other day.

 

It is not possible for a new recirculated BOV to have any effect on your car's tuning or air/fuel if it is functioning the same as your previous recirculated BOV. However, if your older BOV was leaking, you'll be seeing higher boost levels with the newer BOV, hence, effecting your previous tune. Bla bla bla, you get the point.

 

thanks guys
