So, I was looking at APR Stg 1. Is it comparable to APR and what makes it tremendous? Coworker has Unitronic stg 1 and it is pretty quick.
It's hard to compare the two without knowing all the variables, but if you look at APR stage I compared to an out-of-the-box JB1 map 1 setting at 4.8, APR is going to make more power and torque.
I say the JB1 is a tremendous value for a few reasons:
1.) At-home installation.
2.) Map 6 settings gives user the ability to manually adjust boost by RPM to account for supporting mods, fuel, weather conditions and clutch life.
3.) It's about 1/2 the cost of most tunes. Especially when you factor in most* shops are going to charge labor on top of the cost of the tune itself. Yes, some tuners offer dongles so the user can do this at home... if you want to pay the additional $150 (on average).
Like Jake mentioned, there are several advantages to tunes over piggyback units and vice versa, so it really comes down to preference.
