Put all your settings that you changed back to stock, change only table 18994 and table 18995 Make all cells number 10 this should allow the exhaust brake to still work below 70mph too. Please let us know how it works.
Easiest way to find tables: go to edit, navigator, type in 18994 or 18995 in text filter and it will take you right there
