Tuning with E-Manage?

[ItsEcko06]

ok so i know they have the bully dog tuner out for the coupes n such but after i looked across a thread and some1 mentioned tuning with a SAFC or emanage i got thinking.......even though i have an n/a 2.5 CVT would it be a good idea to tune my car with a piggy back ECU? after looking over the price it doesn't seem like too much to invest [$375]. im not saying i will tune it myself but if i had a shop do it for me.....i know i can ask my friend a bit abt it in the morn but i just can't wait...

educate me!!
