Default Turbo Boost

just curious, how do you go about increasing your turbo boost? Is it easy to do or is it something a mechanic needs to do?

PCM on this car controls everything.
I'd suggest browse the forums via as search.
Boost controller allows more flexibility with boost levels.
Stage 1 (Mopar) has more aggressive programming with higher and more sustained boost levels at WOT.
There is a wastegate modification that I wouldn't recommend unless you are very into tuing your car.
The most bang for the buck satisfying change for someone looking to increase performance and fun would be S1. For better titration of boost (which doesn't always translate to mean more power) would be to consider a boost controller.

You can pick up and install a manual boost controller (MBC) fairly cheaply. You can even get a dual stage MBC that will allow you flip a switch to up the boost when you want it. A typical scenario for this would be at the drag strip where you might want lower boost on launch to get decent traction, then flip the switch to get more boost to power you down the 1/4 mile.

While it sounds simple, you need to be real careful about monitoring your Air/Fuel ratio and/or Exhaust Gas Temp. Do it wrong and you can run real lean, which leads to predetonation (sort of the ultimate "pinging"), which leads to burning pistons, which leads to a huge hole in your wallet. Do it right and you've got a fast, reliable car. Keep in mind that such a device essentially bypasses the computer, so it's up to you decide if you want to fiddle with your car this way.

Boost controller is the way to go for an increase. Just like Mike said, too much and you are a sad puppy. Just right and you are king of the world! Well, not really, but you get the picture. Best ways of monitoring are the EGT and Boost gauges. Of course, the Cruiser doesnt come with either, but mu advice would be that if you are going to start messing with your boost levels, it might be worth the investment.

I'll take hoopdiewagon's recommendation a step further (and should have said so in my original post): if you're going to play with this stuff then in my opinion the gauges he mentioned are mandatory!

detailed MBC (manual Boost Controller) install instructions can be found at PTCrew.com - Learn it or Burn it.
