That cam suppouse to pull till like 7k why did he only go till 5.5k?

I had a 2011 6.2.... Wouldn't buy a 5.3 again. You're going to tear that 60e to shreds lol

Welcome to the forum!

I would think with a better converter and if you carried the pull/tune out to 7500rpms, you could get some more out of it.

Then again, I pretty much think that any LS engine with new valve springs should be ran out to 7500rpms, just to see what it has in it. I understand that not everyone shares that sentiment, especially for a 4wd truck.

You people saying to pull it higher are delusional. That cam (well, really, the truck intake) was done at 5500rpm, look at the curve.

It's a truck. Looks good to me.

i'm glad you said it first...The graph is telling you that there is no need to run it any further and the 6.2 is eating that small cam up (which is what you want for a truck). That thing should run real nice on the street and even at the track

221/228? A graph that nose dives after 6000rpm? What are you seeing that were not?

Any cam will only pull as far as supporting mods allow.

I think what is being stated is how the power is falling just after 5500. The cam is no biggie with only .5 overlap. I think the power should pull better that that, past 5500, for that combo. I wouldn't think the intake is causing that drop.

WeDgE1

I honestly thought it would keep making power at a higher RPM. Slightly disappointed, actually.

Truck feels like it doesn't get going until 3k+, then hold on!

Could be the TQ management still turned on, or my tuner isn't all that great...

Sometimes stumbles coming to a stop, or shifting into reverse when it's first started and not fully warmed up. Hopefully it doesn't get any worse when it's -40 outside... Tuner also has it idling at 800rpm; I feel this could be much lower but when he set it lower, it would stumble and die.

Any suggestions?

Yeah, Look for a better tuner !!!

DavidBoren

Find a better tuner.

The intake could very well be holding you back, but I definitely do not think it is the cam. The stock LS3 (204/211) cam carries 6.2L out to 6500rpms, so your 221/228 cam certainly is not done at 5500rpms.

Find a better tuner. That cam should be fairly easy to tune, there shouldn't be any driveability issues with it, at all, ever.

Truck intake and tb. 6.0 lq4. Btr/ljms stage 2 turbo cam. Hp peaked just under 6200 rpm so yes it's DEFINITELY not the intake at fault.

It doesnt carry out with a gen4 truck intake on it. The car intake will pick up 50hp at 6500rpm

SoFla01SSLookinstok

Some people may talk down on the l92 truck intake. It is certainly not the best. There's a thread that shows the inferior flow #'s next to the LS3 manifold. But some people said they have done back to back dyno tests & it was almost the same output. One guy claimed a small gain from the truck intake.

I really don't think it's the intake manifold causing that drop. Heck, I would think the stock cam should carry the power better than that. Something else may be going on.

Personally, I think that any LS engine in decent running order should be spun and tuned all the way to 7000rpms or until valve float, whatever comes first. The thing that is holding back the OP's engine is the tune, not the intake, in my opinion.
