So I've been reading a lot about BNR/Trifecta/ZZ Performance.
BNR seems to be the most popular tune company.
(For the life of me I can't imagine why someone would want a crackle tune.)
But I have major reservations about flashing a tune.
Specifically when it comes to increasing HP. A ton of people online keep talking about cracked pistons and I can't help bur think that the 1.4 wasn't meant to crank out 250hp and be reliable.
I've heard of an eco tune and reports of 46mpg. I'm also interested in what some are calling a " basic tune" that peps up the acceleration a bit.
Can some one share their experience with BNR tunes?
