The symptoms WOULD go away with the MAF unplugged if it is the MAF.

Default I must have jinx'd myself. I just got back from my lunch break. My car has been off the road for

about a month.

I did 2 second gear and 4th gear pulls.

2nd- spike to 16 pause climb to about 20

4th- spike to about 22 drop like a brick to 17 climb back to about 21.

Ironically I bought a new N75 from carson. Just got it today! I don't think thats my problem. I am guessing a boost leak.

My top IC hose I have 2 hoses joined by a coupler. I had to do this b/c that piece only comes in a 3in and 6in iirc and I need a 4in.

Now is a good time for me to just special order it.

What size is the RS4 IC pipe and the bi-pipe ends? I am just going to do that now.
