Hi i have one of these on my turbo-a supra and went to get the car dyno'd today and the tuner said that it maybe faulty? reason said was because it would flash weird numbers when adjusting, then go back to normal. it would read fine and "go crazy" before they could adjust the tune.. i did notice it has a learn mode? maybe that might be the reason? im sure its not faulty..

ive noticed also while im driving it will read like 149 % at 100kp/h in 5th gear and eventually the whole back light display would light up and flicker and then go back to 147-149 % etc.

anyone have any ideas? does it sound faulty? or have any ideas how to tune your car properly with this? any help would be great! thank you
