My family got me a APR Boost gauge for my birthday from Achtuning. I got it install, but I replace the bulb with a red LED bulb to match the stock interior lighting. Install was not too hard, it would have been easier if instructions were included in the kit.
After putting a good amount of effort keeping my car all maintained I'm running into my first problem. With my APR chip enabled and at wide open throttle my car will buck and hesitate between the RPM of 3500-4000 and then run fine afterward. I have discovered a misfire on cylinder 1. I put in a new coil pack and all bucking is gone. I've been told when one coil pack dies the rest are likely soon to follow in the next 6 months. So I'll start saving up to get 5 replacements.
