JoeyF228 they all good and they all have their pros/cons

I saw another thread of you mentioning piggyback tunes? Any reason why you havent tried one yet? You can prob buy a RaceChip from someone here for under $500 or a new one $600 shipped to you.

Again, it all depends what you want out of your car, the routes may change, are you leasing or financing ? first car or have a 2nd car? are you a Do It Yourself type of person or prefer dealer doing everything for u ? etc etc

MissionPerformance as Stubok mentioned has been doing some great stuff from 550, to old DME F10 535 Bmw doubles to taking ocN55 M235 FBO to whole other level never seen before on 91 octane that not even JB4 was able to do for him so reliable.

I'm not a vendor that pushes you to buy a certain product, because certain products dont work well for all engines as it does for others. The N20/N26 is a very different, temperamental engine.

2msport why are they the way to go ? they still cant flash you via OBD2 like Mission, Enzo, etc can for example.
Also, the other guy who had his 228 tuned by GSR, actually lets not even go into that lol. But I do recall someone with a 328 who dyno'ed with his GSR tune and it looked ok.

OP, once again take your time, read the forums, find some info on your similar car or engine who has been tuned and what they have done to prove the tune is gaining something good.
