[QUOTE="maxxedout, post: 1137066, member: 15749"] Please correct me if I'm wrong, but here's what I understand based on everyone's feedback: 61 mm billet (Tow Max)-Good "bolt on" modification that will require minimal, if any, tuning changes to perform properly. Good for towing and daily driving with a noticeable power gain over the 11-14 charger. Should run alright with added fuel from 2015 HPFP. 64 mm billet (Street Max)-Slightly slower spool up than the 61 mm billet, but still okay for daily driving and towing. Drivable as-is, but will require custom tuning to have ideal street and towing manners. More power on the top end and will be able to take full advantage of the added fuel from a 2015 HPFP. The street max should have lower EGT's than the tow max, right? I guess both turbos have their strong points, but it's still a tough call for me. Has anyone gone from a tow max to a street max or visa-versa? The "painless" nature of the tow max sure is tempting, but for only a couple hundred more, I'm wondering if the street max would be more worth it in the long run. The last thing I want to do is buy a turbo, and kick myself in the a** for not making the right decision. [/QUOTE]
