With the base VE settings, it was quite rich but ran good, did a quick change a couple times and things were pretty darn close already. The biggest thing is acceleration enrichment must be upped a huge amount for decent throttle response. Even as of late, I still had to take off careful to not kill the engine (when taking off easy and slow), especially with a cold engine. There seemed to be a little more 'surging' when in 1st gear or reverse than normal. I also seemed to run a bit lean until the engine had some heat in it (basically the opposite of normal), so the coolant temp enrichment could've used more tuning as well.
I think if someone released an SD ROM with the acceleration & coolant temp enrichments tuned fairly well (yes I know every car will be a bit different), it would make the switch very easy and pain free.
The 2 2D VE maps are decent and easy to tune, but they are kind of a pain when running really high boost with a small turbo since the VE goes down so much at high RPMs and high boost, and not so much at low boost. I had to totally redo the RPM VE map when upping my boost to not get insanely rich.
