The pics you are loading up are way too small to see. You need to click on the paperclip icon which will bring up another window which allows you to load pictures dirctly from your computer. After you load up the images, then click the down arrow next to the paperclip icon and select the images to load into your post. Pics of your installation or draw out the routing of the vacuum lines and scan a pic and load up might be helpful.

If you are pretty sure that it is a vacuum leak still, try this. Get a can of starter fluid and where there is a vacuum connection and while the engine is running spray the starter fluid lightly on the connection. If the idle increases, then that is where the leak is. Take caution doing this, as the starter fluid is highly flammable. Do it in a well ventilated area and have a fire extinguisher on hand. This is a common practice to troubleshoot vacuum leaks, but just be cautious. Start first around the base of the intake where there is no hose connection.

Good to hear. If the butt dyno feels good, then a tune will really bring it to life.

Guys,
Still after the test pipe and the reinstalled the m370 intake manifold. It made 246. And it is weak? What do you advice me guys? Should I take off the intake manifold?
The guys here told me to do a compression test.

The tuning shop told me it isn't from the intake manifold. There is a problem with the compression. What does he mean I don't know. Any idea.

Did the tuning shop do a compression test? Low compression usually means that you are loosing pressure in the combustion chamber. The two most common reasons for the loss, is leakage around the pistons from scored cylinder walls or and bad rings. The second would be from the cylinder head gasket or valves not sealing properly.

That seems really low with all mods you've got. Unless I'm misreading something.

It really depends on the Dyno. Mine made 274 on a Mustang and I am quite happy with the performance. I'd probable see 320+ on a Dynojet though. How does the car feel to you?
