Not sure which 1990 Ford Mustang In-Line Modules are right for you? We have over 1502 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:
"Installation was not bad but with the chip installed in the back of the computer it would not go all the way up into position because the chip added length to the ECU. Not too bad otherwise. Performance gains I am not sure about yet because I have other issues to deal with. The car ran good but not that much better. Other engine mods include: shorty headers, high flow cats w/H pipe, Flowmaster American Thunder exhaust, 180d thermostat, cold air intake & underdrive pulleys." —Bryan S from Brewster, NY bought a Jet Performance Module for a 1990 Ford Mustang.
