Can someone help me please, I’ve installed a corksport intake 4 inch with corksport cst5 turbo and corksport inlet manifold. The problem is when I start it up with maf sensor plugged in it starts and stops but if I unplug maf it will run abit lumpy which I understand it will.
Does the maf need calibration to stop this or is the maf broke.
Been told it’s because it needs a tune doing

Cheers chris

You need to calibrate your MAF. Due to the much larger MAF housing, the ECU is getting incorrect information about the amount of air flowing in.
You will also need to tune for the larger turbo. There is no way you can run these mods without a proper tune.
