If your looking for more power I would go with a bigger turbo. A smaller cam to band aid the back pressure just seems like a a lot of lost potential.

I have been in contact with him. He recommended regrinding cam to take some overlap out of it.
I have no clue how old springs are so we are going to try and check pressures maybe they are weak idk.
Looks like a bigger turbo is going to be what happens. Just seems it should do better from reading some of these 7675 5.3 are making alot more steam then this of course I dunno at what elevation though.

Just to make this clear...a smaller cam isn't a bandaid. A larger turbo is a bandaid. Both of those things are indeed ways to solve the problem, but why move to a larger turbo when the one you have now can support more power than you're making? Not to mention its just swapping a cam which is a $350 part compared to a turbo that costs several times that amount.

When choosing a turbo, you pick the smallest one that can accomplish your goals...then you spec a cam to facilitate the needs of that turbo and optimize your torque curve. Follow those simple steps and you'll be a happy camper

Turbo was already on car and I thought it would meet my goals. I went wity a specd cam thinking it would meet it even easier without having to push engine to hard. At this point im trying to find cheaper easier way to correct this issue. Ive been driving car and just short shifting but thats a bandaid if I've ever seen one lol.
