does anyone know around how much hp the rrm piggy back ecu gives you? is it worth the 400 bucks...

 

depends. the more mods you have, more hp.
i say go ecuflash if you know how to tune.

 

how much does ecu flash run? and does it come with like base maps... how much hp do you put down with your car

 

ecu flash is free to download but the cable to dio it is like 200 bux for the 2.0 and like 130 or so for the 1.3 cable if you can find them.

ecu flash you do all your own tuning. the only base maps you have are the ones from your rom on the ecu. or if you can find someone with the same rom id that you have then they might be able to help you out.
