No i haven't run diagnostics, the only noticeable difference with gear changes is 1st to 2nd gear is brutal at WOT. No hesitation shifting up, however if i stuff around with the throttle to listen to the bov, it changes a little awkwardly, like a small free rev. This is characteristic of a trans that needs maintenance or is low on fluid. I will check this in the next 2 weeks as i am a lazy bastard! I do have a long term leak on the trans cooler that could be the culprit. when i get an EBC it will be less annoying swapping between the 2 ECU's as i have to adjust the boost for the stock ecu, therefore making it easier to check transmission behaviour with the auto and manual computers.
