Well, my car is up and running, I work constantly so my friends put the charger on for me.... they all normally work on fox body stangs. Anyhow my supercharger kit for some odd reason came with a MAP sensor... and they were asking me where the current one was. Yeah I wouldn't tune it myself not experienced at all in that dept. Though my sniper base tune seems to have it running pretty well until I get it in for a tuning session.
