So I made the changes and unchecked the O2 sensor (I hadn't done that previously, wasn't sure what to do) and went to the gas station about 4 km away (2 1/2 miles). I could hardly get it to run without feathering the throttle. It seemed to be running hot and still lots of back firing, soft idle but seemingly lots of power when you give it the stick. After I gassed up, turing the ignition back on and it seemed to idle ok so I took it to an empty lot and did the 12 minute thing to be sure (my neighbors must be getting sick of the noise!). Having done that I only got a short ways down the road and it wouldn't stay lit on throttle down to idle so I pulled over to let it cool a bit. I got impatient and just rode it home working the throttle at lights etc. It sure ran like a dog with that tune in it for some reason, but plenty of power off idle seemingly...
I have just reloaded the 20226 tune and parked it down the street a bit to cool off (I need a beer).. I will give it the adaption cycle and annoy the neighbors down the road this time..
I will go easy on the decel with the stock tune and have a think about my next move.. at least it is ridable for now (hopefully). I might seek out someone local that can take a look at the setup, also the dealer said they have a 'rocket guy' so maybe I will see how they handle it.
Thanks for your advice, I will keep y,all posted.
oh, btw I am running 98 Octane unleaded
