How well does the voodoo box work?

What is the most hp you've gotten on a stock internal 1.6l, and at what psi

Can't find cams anywhere where can you buy them?

Anybody wanna get rid of one?

Looking to run 8psi not looking to run standalone.

Not as well as a tuned stock ecu

Just so you know...the VooDoo box gets a boost signal and then adds fuel (via taps on each of the injector lines from the ECU) based on how you adjust two pots in the box itself. It's nowhere near as "smart" as a standalone and is ultimately limited to how much fuel your injectors can flow. By turning the pots, you're telling the box how much additional signal is sent to the injectors, and when the onset of that addition occurs.

FM says (if memory serves) you can go to 7-8 psi with a well-adjusted (not tuned) VooDoo box. I'd suggest you not go beyond 5-6 psi, and don't do anything without a WBO2 (otherwise you're just shooting in the dark and will probably miss badly).
I've got a 1.8, so I can't answer your second question.

Different people will tell you different things about the value of cams. If you're just running a VooDoo box, why spend anything on cams?

Just my $0.02 - tryin to be helpful...

That's it.

What is a better piggyback than voodoo? I thought the stock ecu is non tunable?

Also could I run more than 6psi if I added a msd ignition retard module?

Just stop. Save your money for a few more weeks and then get a used DIYPnP here in the classifieds or buy one and build it yourself. At least with that you won't blow up your stock motor if you have it tuned right. Your asking for trouble trying to use bandaids.

And like rwyatt said forget about the cams. Spend money elsewhere. Stock engine with DIYPnP and tuned well and you'll have a nice, reliable 230whp.

Ok I'm done now

How user friendly is a DIYPnP? Never messed with that kinda stuff before.

It definitely has a learning curve but overall its not too bad. Go download the TunerStudio software and get yourself familiar with it. Once you have the DIYPnP installed you can download a base map and then change a few settings to match your car like injector size, etc.

You will have to install a IAT sensor somewhere post intercooler so you can get rid of the restrictive AFM and run speed density. Please make sure you also have a wideband installed before trying to do any tuning. And you will probably need to upgrade your injectors to 460cc or something.
