U7198 revision

99 silverado 4wd ext cab 5.3
Predator U7198 Software rev 2.12

Is there any benefit to going up to rev 2.13?

Johan sent me a tune to address P0748 code, also changing for 91 octane. If I want to run 87 should I just remove some timing or do I need another tune that will still address the P0748 code?

Thanks
Gary

We will not be able to make a new rev anytime soon for this issue so i sent you a new 87 oct tune and a reg perf with another mpg improvement.

I only received the reg perf tune, did not receive 87 tune.

Thanks
