Just had my dyno done yesterday. Sorry couldn't scan results... But here it is.
Max Power = 369.51
Max Torque = 384.42.

My mods are Long tube,Cat,resonator delete,Flow master,Cold air intake,tune

Your tune looks like mine did before. I got a dyno tune instead and picked up 30+ lbs of torque and a good amount of horsepower too. I'll pull my dyno sheet and show you. I was running super rich.

Something is Really Wrong here, 9:1 is a 20% change in AFR.

What Brand CAI?

The CAI has the largest single affect on the tune.

We typically have to add fuel for almost all aftermarket CAI kits between 5-10% except for CAI brand and Halltech.

The AFR should not be that rich with the stock tune which tells me something is not right.

I would be happy to assist you any way I can.

Remember Email Tunes are ONLY as good as the info and Feedback you Provide to your Tuner.

Just got a few mods installed and put her on the rollers.

Mods are in my sig.

390rwtq

I haven't dynoed my 12 Camaro SS yet but from what I've been seeing doesn't look like I'll do any better than our stock 00 Camaro SS with a LS1. It put down 321rwhp 335rwtq.

GQ4Life · 07-03-2012, 08:57 AM

Yeah the LS1's were a little under rated.. the L99 make the 400HP on the dot.. But the L99 is basically a LS3 with shitty cam setup.. So swap the cam and the variable valve timing and this engine good for like 750HP (650wHP) all day long on stock internals..

Ahhhh, now I get it! Thanks for the insight regarding the difference in horse power.

No need to ditch vvt, the cam is small from the factory, but the vvt makes power. Here is my dyno after just a vvt cam swap, I gained 69rwhp with just a cam swap. I did delete the afm, installed ls3 lifters throughout.

So I took off my Solo HF cats, and put on Dynatech LTs with powercats and ended up with ~352 rwhp & 353 rwtq. The graph below is my before and after. The tq gains are hard to see because the red line is very faded, but they showed some gains from around 4K and up. Not sure if my car is one of the weaker ones or what. I was hoping for a little more, but I know the dyno is just a tool, and going to LTs got me some positive gains, so that's nice

The car has around 2700 miles on it now.

With a 20% drivetrain loss, what do you think I'm getting at the crank? I figure 352/0.8 = 440-ish?

JEFF75645 · 07-25-2012, 12:02 AM

Finally got a Dyno tune and I'm pretty happy with the numbers.

2010txss · 08-02-2012, 09:10 PM

Just installed headers, high flow cats, and tune. I already had adm race cai with bottle relocation and scoop, and magnaflow cat back exhaust. Here is the dyno. Thank you andy at Adm performance in lewisville Tx.
