Hello! I have 2 tahoe. 2012 5.3 and 2016. 2016 we have version 6,2L 420h/p. it is much swifter(?) and more dynamic than old tahoe. Now i am thinking about suburban lt, because it is bigger. i do not want yukon denali. But suburban is heavier and only 5.3L How do you think can i chip suburb to get characteristics like on tahoe 6.2???
