Have gone De-haltech
Background; have had some problem with the car not running as smooth on lower RPM as it was before I tuned it, could be expected with lower tolerance levels (maybe?). Anyhow the car also started throwing back some error codes from the CEL light, started getting a bit worried here so went back and got it re-tuned (checked more like) engine light came on again on Friday, so it was decided to take the ECU out of the equation to see if it makes a difference to the behavior. I can say it does, smoothness is back again in low RPM , engine light has not come on since
The car is now back to run like this though... , scary how you get used to the extra power!
I'll keep you posted, the pure plenum spacer, dirt in throttle body has been mentioned as culprits... not sure though since they are no problems now.
de-haltech is no fun at all...
