That defeats the whole puprose. I was asking so i would know if i should swap it while mu trucks tore apart. I didnt want to go through the hassle of putting it all together, driving 3 hours away to have it tuned, find out it wont work then come home to tear it back down. I know how to check for it after the fact. just wanted to see what others thought about using it.

That being the case, it’ll likely behoove you to upgrade the fuel supply hardware (flow and its commensurate pressure) beforehand to help maximize your combination’s potential.

Your modest power goals shouldn't necessitate any major changes in your fuel system other then injectors. Get some good sized ones (60# or higher) and you should be good to go. Boost is addictive though so I would try to resist "turning up the wick" as they say.
