Is there any tune issues that I should be a ware of before. hitting the track on Saturday??

Will be putting cutout equal distance from 02s and far enough to allow for future header install.

Thanks

I dont know if any tunning issuse as long as you get the opening of the cutout at least 18" from the O2s. Any closer and you run the risk of running quite a bit richer than normal due to the fresh air hitting the O2s.

 

No tuning issues I have them on my truck and havent had any problems with them.

 

I have them on my truck as well and don't have any issues. The thing that sucks about NE drag way is that they wont let you run open headers on street nights so they are pretty much used only to be loud around town.

thanks for the responces.

Seen any improvment in times???

 

my f-body makes a good bit more power thru the cutouts and since the maf is pegged, i had to add more fuel in PE vs RPM than was needed without the cutouts
