Yes you have the good HO engine and a good computor. You should have lots of fun with that and learning how it works and tweaking it a bit at a time is fun and rewarding too. Get on some of the Mustang sites and just learn......just small adjustments until you decide what you want. It is a well matched system as is so go slow. Maybe a bit more timing to start.
