I'm experiencing very rough shifting, lurching and lag when the engine is hot with the A/C on. I've tried resetting the adaptations, and cleaning the MAF, etc. all to no avail. I've got the Dinan software (stage 1, I think from the previous owner) and suspect this might be part of the issue. I like the extra 50 hp, so I'm not ready to give that up just yet.

Anyone with a similar setup and issues see an improvement with this XHP flash product?
