list of the tunes for the i2030 GMC 04 5.3L

[Yeznat]

I am new to the site and the tuning community. My vehicle is a 2004 GMC Yukon with a new 5.3L 327 HP replacement engine.
I replaced the stock 285 HP engine when the Castech 706 heads cracked and trashed the engine. it had 146k miles, when it self destructed. so now I have an engine with more horsepower and 5k miles on it but I was still using the old stock tune. I did not see any difference with the new engine on the old tune, so I found this tuning system and so far I like it.
I have purchased the I2030, followed the instructions and had no issues installing the 93 octane tune.
I removed the trailer brake controller and reinstalled the stock radio prior to attempting the load of the tune as out lined in the instructions. this is a task I would like to minimize every time I swap the tune.
I am looking for a tune that will help with towing a 1974 28 foot Avion travel trailer. Approximately 6k lb trailer
I am impressed with the drivability with the new tune so far but less that 100miles
so with that back ground any suggestions on tow tunes and max fuel economy I know that is asking for the sky but will be happy a good tune that will support the every day drive with the occasional tow of the Avion
is there a list of tunes Specific for the 04 GMC Yukon 5.3L
Any thoughts comments and guidance would be greatly appreciated.
Thanks in advance...

Get a custom tune from CMR tuner Lewis Eaton. That is if you want the absolute most out of your tuner he built two tunes for my truck and they are incredible.

1 - Performance Tune - This tune is designed for use with premium fuel. The Performance Tune will unleash the maximum available Horsepower, Torque and Economy out of your stock vehicle with no other mods necessary! Vehicles will see a power across the entire RPM range with the greatest gains down low. Vehicle will also see improvements in drivability, throttle response, and economy. hp-20 -- TQ-25

2 - 87 Octane Tune - This tune is designed for use with 87 octane gasoline. It will increase HP, TQ and Fuel Economy without the need to run premium fuel in the vehicle. While HP Gains are not as great as in the 93 octane Diablotune, this tune wakes up your vehicle's throttle response, power, and improves overall driveability. HP-13 -- TQ-18
