So you read the links?

.4 smaller than stock, pushing approx. 4lbs boost more than stock... It's not the 3.4, it's the supporting mod's that go along with it and tuning for NO knock that makes the difference.

Read up, then read some more, not just here, everywhere. The 3800 platform has been around a while, there's plenty of material available. Then when you feel comfortable, make a plan and ask questions, and read some more...

Give a man a fish...!
