I checked with one tuner who is in the Marietta, Ga area. It seems their employees want to talk down the Oft and talk up the Ecutune. I would like to have it dyno'd and tweaked for what the dyno results show. They want to sale you the ecutune because they say its easier to tune. Any help would be appreciated. Thanks Steve

Every tuner likes to use the system they are familiar with.
Most tuners like to lock the ecu so you cannot read or alter thier tune, so many wont tune with opensource systems like oft, tactrix ect.
Ecutek has some advantages with FI cars and theirs some cool features but tuning on na cars is fine with opensource tools like oft
OFT tunes are pretty good if you stick to the mods they were designed for.
As you have changed intake (although the grimspeed is very close to stock maf scaling wise) i would check your fueling make sure your ltft are low and commanded afr and measured afr are close under wot.
once you have that sorted check for knock and smooth the ignition timing in that area, then your prettly well good, unless you wantvto add any utility tweaks like fan temps.
with standard type mods on an NA car their will be little to be gained getting a custom dyno tune.
