I think the cruise not working is a symptom not a cause for poor power. What are you using for a speed signal for the cruise? Did you hook the CAN systems together on the car?
The speed signals for cruise and transmission operation and speedo all come from the ABS controller. I would think for the cruise to work in the ECU you would have to have a speed signal from the ABS. The engine ECU may want a speed signal to match the car signal in order to work well. Maybe you have already hooked into the can and I missed that, since you have cruise sort of.
There may be a underlying code in the ECU that is not showing due to tuning away that may be causing a limp mode. I know on my common rail swap I was working with Charlie at Kerma on it and he told me that he could easily make all codes disappear and never be seen again, but would rather leave them live during development and extinguish them one by one in order to more fully learn what is going on. I have the q-pro so it is just a matter of flashing in a new file each time, no biggie, and he learns the inner workings and repercussions of eliminating different things. I do not mind being a guinea pig, so to speak.
Unfortunately it has been snowy and cold here so I have had little drive time to swat bugs. I am not using cruise or any speed signal at this point due to running in a non ABS car, though I did do some research into signal generators and converting signals into CANspeak through the ABS controller. I figured if I wanted cruise that is what I will do.
