OFT with Catted headers
 

would the OFT stage 2 UEL tune be alright with the
ft86speedfactory CATTED uel header / perrin 3" catback and overpipe

Stege 2 UEL will Probably will work with good fuel, just log for knock and AFR to see all is ok

however the safest option would just be the stage1 tune

email openflash guys to confirm

I thought the stage 2 header tunes are designed to take advantage of the lack of the cat and may actually run too hot for the cat under hard driving conditions.

yea the stage 2 is for catless so that what i thought as well.

and by knock im assuming you mean, engine knock noise?

I am using 91 Octane Stage 2 UEL OFT flash with the FT86 SF catted UEL headers. Stage 2 UEL was recommended by Shiv. Great boost in performance. I also have the the TRD intake.

On the Auto Generate tunes, there is a stage 2 EL Catted, so you should be okay?

Could you share the log if you have any please?
