I just finished installing my mac l/t's and o/r prochamber, to compliment my existing mac catback. I started it up last night. I know I'm supposed to have it retuned with the addition of these parts, but I took it for a very easy 1 mile drive just to hear it.
I was very disappointed, I had a sort of raspy, almost hollow tone. The car also ran pretty... not good. It studdered all over. I'm scared ****less that I have an exhaust leak, as that would requre the removal and re-installation of virtually everything I just did to install the headers.
I got new FRPP gaskets and threw a thin bead of red RTV sealant on the block and headers. The only thing I can think of is that I didn't tighten the egr fitting really tight because there was no room for a wrench. The O2 sensors are hooked up for sure. I know my spark plugs were starting to go the week before I began the installation, I guess that could be my problem, but it seems pretty bad.
I'll be getting my tune hopefully tomorrow and loading that in, is it possible that the reason it's running so bad is because of the lack of tune? Anyone have any insight?
Thanks.
