Hi, while I skimmed through this thread I still have some questions.
Might I suggest this:
https://www.google.com/search?sourc...=APR+Stage+1+Warranty+Issues+site:golfmk6.com
Can someone explain please to me in detail (for a not-so-knowledgeable) car person about APR Stage 1? I feel like I want to do it, but I don't want to void any warranties. That, I am extremely nervous about. I am never going to go beyond Stage 1. And I'm nervous about damaging the car.
Let me put it this way. APR Uses the same principles and engineering fundamentals and practices that we do. Rapid Prototyping, CMM Romer Arm, etc. etc.
I trust nothing else but APR to be the performance parts in my car. I'm currently APR K04 tuned and have had ZERO ZERO ZERO issues with it. APR is strict with their quality standards and customer support. I promise you cant go wrong with them
What exactly is done? What does it effect? How much does it typically cost (sale or not). Can it ever be returned to stock? Do any aftermarket parts need to be purchased? How does this improve gas mileage (from what I've read)?
While trade secrets will never be shared, I will say that certain values are modified within the 3D map. Its not a simple system and it takes LOTS of experience and know how to understand what you're doing.
Some companies run modified maps that act as a "standalone tune". Somewhat. When you modify the component protection you immediately take the ECU out its own fail safe mode and can really do some damage to your engine. APR does not do this, this is why they are regarded as one of the safest tunes out there. Not sure what other companies do this. I'm sure they'll chime in.
You car can be returned to 100% stock if the flash ever needs to be removed.
You do not need to purchase aftermarket parts to run it, but you certainly can get some extra HP out of just a Stage 1 tune and Stage 1 intake. Best bang for the buck ever!
Gas mileage has been reported to go up. However, you must stay sane enough to keep your foot out of it
I have APR K04 and got 2 MPG better than my stage 1 tune,.......if I can drive it sanely
And anything else you can think of.
Thanks...greatly appreciated!
PM me for a bit more details if you're looking to really get into the VAG mod scene. Its quite extensive, but I can try and help point you in the right direction.
