I'm always considering my biggest bang for my buck so,

If one of the largest benefits of the hotpipe upgrade is to provide a more consistent boost reading resulting in the computer not pulling back on the boost a bit then wouldn't getting your boost reading from the cold side of the intercooler give the same results?

I know there can be more benefits from doing either mod but it just seems like with these two a major part of their benefit would be to solve the same issue.

The hotpipe upgrade fixes the surging we have and the intake chop we hear when we have a intake. It also helps the turbo spool faster and respond better to throttle input. Another plus is that the new hotpipe will also not heat soak as bad as the stock one. If you take just the mid section down of the hotpipe you will see it is a thick metal compared to actual intercooler pipe.

So there is a few more benifits than just it stabilizing boost pressures. If your wanting to get a boost reading you want to do it off the intake manifold or right at the throttle body

The wastegate hack as some call it lowers the pressure seen by the wastegate which in turn raises actual pressure and has the chance to push the ecu into limp mode (right around 19 psi this happens). It will work fine for those out there that can't seem to get over 16 psi but like mine at sea level I see 18.4 all the time in stock trim. It will fall off in the higher rpm but if i was to do the hack I would spike over 19 psi and instantly limp. This is where the hot pipe comes into play. It not only eliminates the tiny factory piping allowing more volume and lowering the velocity but also eliminates the spike of pressure the wastegate sees with the smaller pipe. Typical pressure reading I would see with stock piping at the turbo would b 21.5-22 psi and 17.9-18.4 at the intake, with the hot pipe upgrade it was 18.7-19.3 psi with 17.9-18.4 at the intake. So really the benifit from the hot pipe is better for the turbo, increases volume of air to the IC, increases power without increasing boost pressure and also helps overall drivability.

I really need to get something to monitor my boost. If it's not that high then the hack might be worth it. Although I don't like the name it's been given.

And the hot pipe would be more easily reversible...

Honestly if the hot pipe gives a similar result (more consistent boost reading) plus more then it would be the way to go.
I really need to get around to doing one or the other.

We just need a one piece hot pipe made for us...

I saw guys piecing then together, and I saw some pipes at lowes to night also. I am in if we get a kit or one piece put together.

From my understanding tork said the 15 ecu maps puts the car into limp mode at 20-21psi. If your hitting 16-17 like Jason said then yes the hack will work great but if hitting 18 like I did when stock I would honestly just do the hotpipe and get either a boost gauge or the torque app.
