Performance wise only:

What can you do with k-pro that you can't with emanage... (ONLY PERFORMANCE WISE)

 

I don't know for sure, but I would bet that part throttle performance would be much better with the K-Pro.

 

which is not important!!!

 

Okay, so you only drag race? Then I guess K-Pro may also have some features for launch control that may not be available with eManage.

 

ROFL

 

launch control mm..I knew about that.. but I do not consider it...engine power..HP gain or torque....so still .. I didn't get an answer...

 

Any of the standalones and most piggy-backs will get you the same exact full throttle output on a dyno for a stock or moderately built NA setup. You would have to go with something pretty exotic before there would be a difference at full throttle output. The real difference is with driveablility and part throttle performance, which is probably more important than you think. If you want to do any street driving, road racing, or autocrossing, then part throttle performance is going to be very important.

 

gernby, street driving not important because it's my racing car only... I go to speedtest or autocross,... and true.. partial throttle is important for that ....

 

Definitely Kpro for part throttle tuning.... or even AEM EMS if you don't have to worry about emissions

Either way both will be better than the EMU.....

Honestly your biggest issue will be the tuner and what he is comfortable with.....go with what he recommends

 

The Emanage Ult handles part throttle tuning...

How is the Kpro better at handling the part throttle tune?
