I love mine, love the logging capabilities, also with the latest firmware you can run
lower boost than stock in 1st, 2nd and 3rd, really really helps with launches!
If you buy new you will get George's
help and support in setting up a custom map 6, he will check over any logs you send him to make sure everything is good, although once you've got to grips with it you'll soon learn what is good and bad! Or just set it to map 1 and leave it alone with yours been a manual!
I'm back at the Dyno next week to see how it compares to my previous Jb1, but a few days ago me and a Golf R did a few pulls, I was alone but he had a passenger, he is Stage 2, didn't say who's map though, each time we left in 2nd and he initially got the jump, but, once I hit 3rd I was pulling him back in, by the end of 4th I was slowly passing him!
Here is an example of the kind of logs you will be able to pull, did this one just a few days ago!
