Gents, I have lots of questions. I just installed the Stealth 2 with 6 programs. I only set the 50 hp gain due to the cautions about having some kind of gauge system. I am really looking for mileage plus added performance. I am getting ready for about a 1500 mile trip. I normally tow on a daily basis....maybe 3k. The manual didn't give much info on the settings. Will I be ok to tow at the 50 setting when I return? Is that the optimal setting because the next jump is up to 70 hp? What is "Limp mode" on the tranny and how do I avoid it...and what do I do if it goes into it? I have a 02 LB7 with 78000 on it. No other mods to date....planning on a Volant cold air system soon...maybe larger tires. Thanks
