Update: My ZF milkshaked and it is currently being fully rebuilt. I expect to have it back in the next few days. I was offered a secondhand ZF as a replacement for my damaged trans, however I decided that I didn't want to stuff around with a second hand box and the associated programming issues when swaping them between cars. As such I expect to hit the drags again soon with my MT streets and hopefully run into the 11s. I have previously asked XFT to tune my trans and they informed me that due to an issue with my XCAL3 firmware, they would need to tune both my engine and trans at a cost of $1,500. Simon said that my engine tune was pretty close to spot on, so spending $1,500 and only benefiting from the trans tune was a waste. Can anyone tell me if they think that the benefit derived from a trans tune is worth $1,500? What sort of improvement in MPH and ET does a tuned trans yield over stock? Andrew
