Proposal for an tune on my Tahoe 5.3 2007 LTZ (Germany)

[poertsch15]

Hello dear community and professionals. Currently, I've bought an I1000 on eBay and already turned off the DOD under the Stock Tune.

Now my question for you. I myself live in Germany and will often be traveling with a caravan now. Which further tuning would you recommend to me to get a better performance. Or do you have any tips that will make my Tahoe a little fresher?

I would like to mention that I installed an LPG system from Prins VSI 2.0.
Is very common in Germany to make such a conversion because of the high fuel prices.

That's why I did not dare to go to the Octan Tunes.
I would be glad if you had tips and could tell me your experiences.

One more question, I have rebuilt my air bumpers against completely normal. Now I always get the error displayed service suspension. Can one also disable by the Intune.

Thanks so much and Greetings from Germany Markus
