What are you having trouble with?

There's many variables that you likely will never touch that are defined.

Most of the time it's VE and spark table tuning.

 

Tunerpro is a great program, easy to use IMO if you want to keep your stock ecm

 

Sorry if this was already asked, but is this for a carbed or fuel injected 2.8?

 

u can do it on a carbed v6 as well but u would need to buy a edelbrock 4bbl intake and swap on a holley 390cfm no vacum secondary carb , and modify it for boost

much better off just swaping in a fuel injected v6 first since the carbed v6 has a weaker crank in it

What do you do with the vacuum lines? will it work if leave them how they are stock and will the brake booster still work? will i to have to doo any tuning to the ecu if i am only running 7psi of boost and it looks like you changed the o2 sensor, can i use the stock one?

 

This is an old an outdated thread. But anyway, 7-psi is approximately a 50% increase in power. It's not the matter of the ECU handling the boost, but your injectors,.If your engine is making roughly 150 horsepower, and you throw 7-psi of boost at it, you are looking at about 225 horsepower. That requires at a minimum of about 18# fuel injector flow. So there are two ways that you can do this using your original equipment with a few additions. One, you can tune (or have tuned) your factory 15# injectors at 65-psi of fuel pressure which will give you your 18# fuel flow... which I honestly don't recommend, and two, keep evrything as is and buy a Vortech adjustable fuekl pressure regulator which will increase fuel flow whenever needed (in boost), this was you can leave your factory tune as is. In your case I would go with the latter. The right way of course would be to install the proper sized injectoirs, wideband, and updated ECU, and tune it to perfection, but at just 7-psi of boost, you don;t really need to re-invent the wheel. Take your pick... just remember to back timing down a tad and lock it if you go the non tuned way.

As for the vacuum lines, use check valves where and whenever needed.
