Just go full send. You’ll probably end up there anyway.
It is what happened to me. I danced with the idea of more power even though I had 3 years of warranty and 1 year CPO warranty. . Even bought a JB4 and wanted to go that route. For me once I saw how the JB4 was routed, I had to raise my car to get to the bottom plug to remove each time and per Burger Motorsports " While JB4 strategies for fuel and ignition control vary by platform -" I was out. I did not want my car to run harder on things or put added stress on parts that it did not have to. I wanted the ECU tables from the flash tune to control the fuel and ignition timing properly as the JB4 is basically a hack for the ECU. I tricks the ECU to send more boost and there are things it can not adjust properly for. The APR tune will adjust more tables properly such as sending the right ignition and fuel timing. I have seen a lot of forums where fuel pressure is an issue with the JB4. Also per Burger Motorsports " a few things the JB4 just can't do including changing fuel injection timing raising the RPM limiter, adjusting valve timing, raising the speed limiter." These were all must haves for me. Also the fact that the auto start and stop gets re-programed to always on with the APR Tune is another must have. With the TCU tune I am able to get more clamping power on my 6 speed DSG so the extra horsepower is accounted for when changing gears. I have launch control now with better shifts. Another must have is I can see what gear I am at all times, not just drive mode. This is super helpful and damn right practical when I want to get around cars on the freeway , I just down shift into the right gear and pass.
Fun Factors of Tune
1. My car now. I am in it for the long hall and made a decision to keep the car because I love it. I am now in a committed relationship, totally connected to my car. If anything happens I will assume responsibility. TD1, power train etc.
2. Getting thrown back in my seat each time the car hits at a specific RPM exactly with perfect shifting Timing with the DSG Tune
3. Hitting the gas on a straight away around town and hearing my girlfriend shout while her glasses fall off her head ( doesn't know I re-tuned) sounds trivial ? Maybe, just feels right knowing I have power on tap. I do not drive slow because of the power you see, I drive spirited and when I do it pulls very hard and gets that smile on your face or laugh.
4. You are not going to be tire hopping all day or tire spin, you are not mashing the pedal at full throttle always at every given second and honestly I was getting this at times without the tune, it is just the nature of the beast with FWD period.
5. Satisfying feeling that this car should have came like this from the dealership and I have R level or even slightly more HP and Torque - I went with APR Stage 1 High Torque 316 HP/340 Lb
Torque.
This is my experience, good luck on your journey.
