I mean realistically, it's your money your car. However, the gains from each one are already rather slim. Yeah one might give you more mid range torque or more torque specifically at 2500rpm or something, but they aren't going to be much different for the price you'll pay changing them. I will say that all three of those tuners will give you strong, safe power. Personal preference for the rest.I'm currently stage 3 and have a stratified tune and freektune, but I've read some great things about JST so I'm wondering if it's worth it to purchase their tune if I already have two others.
I guess by ignoring what I said he was hoping I was lying? :lol:OP, Brian is right jumping around especially with the stock turbo won't help you but burn up money in your pocket.
If it's about response time then a change might be warranted. If what you really want is a serious bump in power, upgrade the turbo and there is no dancing around that. Much cheaper than taking a hit on your bottom line to get a RS or Mustang GT.
