you could use the cigar test, or pay an hour labor to have a smoke test done, if nothing else you will know if anything is leaking and where its leaking from.
the other thing you can use is a can of throttle body cleaner to spray around the base and plenum, throttle body and where ever else you think needs to be sprayed. lines you may just have to gently feel around

I sprayed throttle plate cleaner around the runners and vacuum lines to no prevail. The code comes on now IN GEAR with brake applied. I assume its because the idle drops down so low and it sees low vacuum?
If you brake torque it in gear, the car hesitates, and pops both through the intake and exhaust. Like I said it does this when warm after warmed up. Could this be another OPTI issue?
I unplugged the MAP sensor and it seemed to run better at first but then had the same symptoms.

Try taking the MAP off and checking that little rubber donut that the nipple mounts too. Is this on a factory tune or has a tune been applied yet?

The nipple was there. It's a little scrunched up. Maybe ill try taking it out and plugging the hole and seeing if that helps. It is in tact though.
The tune has been changed. Email tune from madz28

Eek, haven't run into a good experience with a tune from madz28 yet. Not saying it is your problem, just saying there isn't a good track record there.

Noo it was doing this before the tune, not the cam. But anyway I had a good mechanic friend listen to it and he said it sounds like timing, so apart it came.

Good stuff, it definitely helps in diagnosing when you can see and hear what you are working on

No definitely, I do the same. Its just tough/frustrating when you can't see or hear the car in question. Keeps you sharp at the same time though, having to consider all variables that are second nature when you are there in person.
Go race it!!!
