Hey there JFG92.....your comment is the only positive one here....been toying with the idea of trying this chip on my 2002 Eldorado ETC North Star Engine for the mileage is not very good as it ranges in the city
about 14-15 mpg and hoping to bump up the HP, as well.
From the comments I've read here I wonder if over the long term, any damage occurs in the engine and I
see your comment made bak in 2011 so I wud think you've had enough time to evaluate the results of this
chip....let me know, please.
