5T4R7ET N/A Posted March 23, 2014 Share Posted March 23, 2014 the only way is to use a piggy back ECU like E-manage blue or ultimate Quote Link to post Share on other sites

mech5107 Posted March 23, 2014 Share Posted March 23, 2014 Put on some 4efe or 5efe injectors. 4efte injectors are too big for n/a. Quote Link to post Share on other sites
