Want to do tune for stock set up. Would the JB4 be fine or is it better to get a flash? Just want better overall performance out of a DD. Which flash tuner is recommended if I go that route. Want something that is basically just plugnplay.
As long as you are not warranted. I would get it tuned for sure.
Unleashed, AJP Turbo ( if he is still doing it ), Gearhead.
Others may chime in but those are who I would use.
Unleashed has excellent customer support.
Gearhead has auto octane tuning.
AJP is the best for top speed per say. I used AJP and his tunes rocked it out.
Today. I would get an Auto Octane tune via Gearhead and they do a great E30 tune if you have ethanol around. 93 is good enough tho.
I pretty much only have access to 91 w/10% E or nonE 91. Above 5000
Non E 91 is a good choice.
5000 ft is tough on turbo output but the tune will be good.
