Question OFF PCM Controlled Boost Possible??

I have had two SRT-4'S in the past and was wondering since the displacement is the same with the motor and turbo is there a diagram like the SRT-4 the boost off PCM control with out a stage 1? The vaccum lines are the same.

I know they have not made a aftermarket wastegate for this car especially for the 2006 PT GT Auto/triptronic yet not sure if that would ever happen lol.

But my question is i wont get a MBC cause i know the PCM will take away boost which causes fuel cut and could be dangerous to my engine but raising the boost up to 18 to 19psi by tricking the PCM is that possible?

Kind of like this shows a diagram for better understanding.

Can someone explain on and off PCM control? - SRT Forums - SRT4, SRT6, SRT8, SRT10 & Dodge Forum

you can run the same agp turbo wastegate as the srt4. and also can run a single stage manual boost controller through the turbo solenoids, I had one on my car and I ended up with a overboost code. just takes the pcm reset (unconnecting the neg battery cable) to reset it and get rid of the overboost code when it occurs.

The Cruiser got the 2.4 engine first in the '01 and later in '03 the Cruiser GT and the SRT4 got the turbo versions at the same time. They are identical engines and turbos, etc. The intercooler, intake mani and mufflers are about the only differences. I even know of a few Cruiser GTs that are using SRT4 PCMs. So anything you can do with a SRT4 you can do with a Cruiser GT. I ran a AGP 50 trim big turbo @ 25psi in my GT with a custom exhaust mani, external wastegate and a MBC. I by-passed all the solenoids which eliminated any PCM boost control. Plenty of other owners have kicked their boost up to 18psi with just a WGA and all the other stock PCM/solenoids in place.

The camshafts are slightly different...... same specifications. They will physically interchange but will not run. The PCM also has a different calibration on the Turbo models between SRT and PT Cruisers.
