good to hear sadly mine failed from faulty firmware issue, and left the car immobile had emailed burger said try recovery didnt work then said you should buy a new circuit board..lol
got fed up with it and returned it luckily i got a full refund.. went for a proper tune and gained an extra about 10-20% more power across the whole rev range.. and all the while running 2 psi less boost, just wish i hadn't of wasted the time on the jb4.. although i understand why peope with warrenty go for them.. also the logging and afr etc are nowhere near accurate.. it just makes estimates based on calculations, logging with vcds showed the correct readings..
