so i have a bit of an issue, i installed the 74mm throttle body, with larger maf housing , with the stock maf sensor. so first thing, it didnt have an o ring inside , simply some silicone gasket i think , it ran fine , so we used the same thing this time , the car doesnt idle properly now it feels like its sputtering and the whole car rocks side to side slightly , i did a throttle reset , didnt help , this was worse when i had taken off the mesh screen and plastic guide ,now i notice the issue stops when i cover part of the intake , so it seems like the car is getting too much air. will this be fixed by a eurocharged retune? the car an fine on the freeway , or basically anywhere above 1000 rpm
