Hey guys, here's my mod:

Cobb AP Stage 2 Map
Cobb TBE and up-pipe
Cobb Short ram Intake
HKS SSQV

I'm thinking of going to MN to get a custom tuning for my 05 wrx. But I got a question... After tuning, does the engine stay the way it's tuned or would it kinda get lose and I'll have to go back and have my engine tuned again to remain the same performance.

Advise please......

 

The AP retains the map and flashes the ECU. The reflash is not affected by things like battery removal or disconnections. You don't lose custom tuning although the ECU will adapt to things like an occasional bad tank of gas (wrong octane) - it'll run lousy until the right gas enters the system again. If something were to go wrong, the AP retains the maps so they should never be 'lost'.

Just remember to run the same fuel during tuning that you will be using with that custom tune. The AP can store multiple maps so you can have one for race gas (100+ octane) and one for your local pump gas.

the butt dyno over time will make you feel like you are losing power because you get use to it. then you will be wanting more mods.
