JB4 Installed- All smiles here

ak_47 · 03-28-2013, 10:57 PM

Came home early from work today to install JB4 on car, and damn..I am impressed! The power from the tune is amazing, and feels smoother than stock at low RPMS to me. The "canflap" open option is great as well, my car sounds so much nicer. Its also nice to finally hear my turbos spooling as well.

I ordered OEM replacement Spark Plugs to install as well, but couldn't find a reasonable torque wrench. Im hoping the very slight rough idle goes away after i swap out the old ones.

Thanks Burger!

congrats on your new tune!

with regards to idle. don;t get your hopes high. Plugs made it slightly better for me. but I changed a lot of parts and did carbon cleaning to get to perfectly smooth idle. I felt each piece contributed... (carbon cleaning, plugs, coils, tmap sensor)
