I have bone stock 335i with the procede N54 3-30 DIC beta maps installed.The maps are not customized.I use factory recommended gas-premium.No plans for any upgrades at this time and point.Would you recommend map1 or map 2 for everyday driving ?

Run map 1. 13.5 lbs of boost is good enough for a stock car in Flordia heat.

how about my car has catback exhaust and drop in filter which map should i use?
and if after i got catless dp and intake, which map should i use?

Map 1 until you have an intercooler and downpipes would be my suggestion

+1 on what Brey335i said about having a fmic and dps to run map 2.

You're only talking about an extra 15 hp or so to go to map 2. But that is only if you have the supporting mods. There is a good chance your car will be slower on map 2 if timing get's pulled.

You can find out for yourself by logging. If your ignition stays above 10 on a 3rd gear pull you should be OK. If there's timing drops lower boost and repeat. I like to do several pulls in 3rd or even an 3rd to 4th gear pull.

If you had one of the autotuning maps and monitored how the proceed adjusted boost you'd have a good idea of the boost your car likes given conditions (octane and temperature). No need to fool around with ignition correction since it's now dynamic. So leave that value at the default.

What Brey335i said about map 2.

With dps you could run map 2 but your stock fmic won't remove enough heat to keep inlet air temperatures down. Before I got my fmic I noticed that the car was significantly slower after only one pull or sometimes even a short pull from 3,000 to 6,000 rpm in 3rd. You'll loose lots of power up top in the higher RPM range too (it feels like the car runs out of breath up top). That's where our cars turbos generate a tremendous amount of heat. So one trip to the upper end of the RPM range in one of the taller gears and you'll heat soak and need a few minutes to get back to full power.

After an FMIC it's a different world. Consistent power even in warm temperatures. All of our cars can heat soak but with an aftermarket fmic it takes a much longer time to do so.

Like topspin said: consistency is key. I have managed the same exact time on the drag strip on 5 consecutive runs with a 6AT and fmic, dp, intake, charge pipe, tune, etc.

Before all my mods, I always had problems with heat soak and would have to let the car cool down way longer than what I do now...
