Flash ECU...any problems

Any ever had any problems after they got their ECU flashed? I'm planning on getting it done but I want to know the pro's and con's of doing this. Note: I don't have any other mods.

no problems at all with my flash.
i would suggest at least getting a larger pulley before doing the flash.

that would depend on the pulley size.
if its too large (175-180) i think it would need a tune to run properly and u would definitely need to upgrade the stock heat exchanger.

with smaller pulleys u can get away without doing an ecu tune but tuning would maximize your power gains.

I know this might sound dumb.. but ECU tune is different than Tuning ? is that correct? what do they do when they just tune? without Flahing my ECU and new ECU.

Also with a smaller pulley, what would my expected power gain?

ecu tune, flash and tuning is pretty much the same thing.

when they custom dyno tune your car in person they still end up flashing your ecu with the new and optimized parameters.

someone please correct me if im wrong.
