I have an AEM intake in the car, everything else is stock. I've been told a LOT that the intake ***S the MAF. And even with a reflash it'll get screwed. Is this true. Should i pull it out and put the stock airbox on or pull the cone filter and get the ARC airbox ??

 

I would never run an intake without tuning. One long boost under some conditions could cause a very dangerous detonation situation (especially on 91 octane). The stock ECU will run very lean in the mid band due to the wierd MAS readings it is getting with that intake.
