Is the regular emanage adequate enough to tune around 600 whp or do I need the ultimate? If it is not needed that will save me some money. Thanks

 

it'll work, but the ultimate is soooo much better for datalogging and fine tuning...

you COULD use the blue emanage...but for a few hundred bucks more (if u have a blue sell it and upgade) you could have a piggy back that accomplishes almost the same feats as a standalone for 1/3, if not 1/4 of the cost

 

i agree, tons more options you can do plus the target a/f map will save you money on the tuning part justifying the extra cost which really isn't much anyways considering the eu comes with the "support tool" cd too and is an extra cost for the e blue.
