Hi all,

I've spent the summer tinkering with this new G92 Iroc. Finally getting close to where I want it to be, but I'm trying to get my fuel mixtures dialed in.

I have installed the racetronix walbro kit, new southbay 19lb injectors, southbay adjustable fpr and a new summit 58mm throttle body. During this whole process I also removed the leaky intake manifold and did a light port to the upper and lower plenum, as well I port matched the intake for the new throttle body.

The long and the short of it is that my car now drives a LOT better than it did when I bought it, but I am still getting code 32's and my BLM is showing in tunerpro around 148-150.

I have tried the suggested raising of the fuel pressure to 50 PSI and it helped bring it from 150-155 to 146-150.

Now I am thinking that maybe there is a vac leak somewhere, but I honestly don't even know where to start checking. Obviously I have had a look at all my hoses and nothing shows as visibly unplugged...

Worth noting: I replaced the common sensors when I did this tuneup as well: IAC, TPS, CTS and O2.

Help me fellow third genners!
