Purchased my 03 in November, drove it home 300 miles the day I got it and it ran great, didn't miss a beat. Parked it for winter as soon as I got home and gathered parts for the next few months. Just recently finished installing everything and had a reputable tuner from the site work me up a base tune. Downloaded the tune and started the car for the first time since November and it will barely stay running. Idle is all over the place and it's really choppy when giving it throttle. When I purchased the car it was running the stock MAF with a Mafia setup, I swapped this out for a BA3000 MAF as well as did the EGR delete. I unplugged the maf while the car was running and it smoothed right out, figured the MAF was bad. Installed a new BA3000 and it does the same exact thing, unplugged it and it runs smooth. When the maf is plugged in, its dumping the fuel to the car, you can smell it, plugs are wet, and the afr's are off the charts. No CEL is triggered. Double checked all the vacuum lines, all good. Reached out to the tuner weeks ago and haven't received a response. The odds of two bad maf's is very unlikely, do you think the tune is way off the mark? Thoughts?
