I have a 2000 GMC sierra ecsb and was wondering if the programmer for my vehicle will have the TM settings that I could adjust? And can you change these if you load up the 87 oct tune or only in the peformance tune? I am really interested in buying this if you can change these settings. Thanks

Yes, you have the ability to modify the TM settings with the 87, 93 or even the stock tune.

Thanks
