Don’t get me wrong, Gavin knows more about Nissans than most people – however to cut a VERY long story short, I bought a second hand Q45 throttle body from a wrecker, unknown to me at the time the wrecker swapped the TPS unit for a ca18 unit, which meant the car wasn’t tunable… My car was with Gavin for a full day and he couldn’t find what was wrong with it.
I took it to Matty and he found within 5 minutes that the TPS had been swapped over, we put the correct Q45 TPS in and had it tuned…
I know where I will continue to keep going back
