I agree the maf configuration needs to be changed back to oem - this is a strong suspect as the first troubleshooting step to take. Although an AEM might fix the problem, that's like fixing a cut in your finger by replacing your arm with a robotic prosthetic. A whole AEM setup is $2500+, and this could likely be fixed with a few hours (or less) of troubleshooting with the existing setup.

yes the owner he's my best bud no money just help him out mybe i'll get a 6-pack of budlight lol it looks like a DSM setup with the maf like a blowthru he wants the AEM pretty bad i agreed that the AEM would give him a boost of performance! i hooked up the computer to the car and it pulled 5 codes fuel pump relay, coolant temp sensor, TPS sensor, and turbo boost pressure sensor *2
