Hi bud, does it lose power and have a delay in making up boost?

I had a similar thing on my car, the but mine has the ZF8 Speed gearbox and it has been serviced and in good health too. However, the xhp sorted it out.

Hi yes it had a small delay Yes, so would you say it is the gearbox itself or what is it

Well honestly everyone or rather no one could give me an answer on what it was, and as I said it was already serviced and in good health and the car was stock so something else was a miss and not directly gearbox as in hardware.

I then did software and Downpipe on the car...still had the little delay in power....then upgrade the spark plugs and that helped a bit also....but when i did xHP software for the gearbox, it is totally gone!!!! 

Bearing in mind, I had the TCU adaptations reset also before doing this and it didnt help. 

So that was my route of action...seems the plugs and then xHP was best help. I have no idea why it did that and not many people locally suffered with these symptoms but I have read quite a few overseas that have suffered it but also found plugs, coils, xHP and a host of other things to fix it and cannot pin point to the exact issue why.
