how does having a duel stage boost controller effect tuning? if i have my motor tuned for lets say 15 psi for the track and i switch to 7 psi for driving around town, will my fuel maps be all screwed up when using the lower boost setting or vice versa?

 

no...7 psi and 15 psi would be two different positions on the map..so no need to retune.....only something like changing your intake or exhaust would effect your fuel maps.
