custom hand-built intake maf issues.......pissing me off.

[soldier_1983]

i built a custom, one of a kind, intake pipe for my 1.6l. i had the maf in the correct position and everything was connected right. i even flipped the maf just in case. i need some help.... she doesnt wanna run right.

if you have the piping diameter different, the flow rate of air through it will throw the MAF off. What sizing are you using and how does it compare to the OEM tube or an aftermarket.

im using the stock tube set inside the pipe that the filter and maf is on.the the stock pipe is 2 1/2 inch inner or so. and the the pipe im using is 3 in.
