All were very near the same temp and humidity
engine temp was about the same for all
My pre tuner 219rwhp 288rwtq
87program, 87oct 223rwhp 292rwtq
perf/towing,93oct 225rwhp 299twtq
performance,93oct 227rwhp 300rwtq
All the way I drive, belts, air filters, etc.
Then I took out the K&N drop in on my home brew CAI
228rwhp 301rwtq
I maxed at 8hp, and 12tq, over my already nice #'s, using the Superchips tuner, max.
Objective as you get.
My pre tuner mods are:
homebrew CAI with K&N drop in
ported 68mm TB
HO intake-an 02
HO cams
NO belt driven clutch/fan
NO third cat-I like the sound!
3923's a mod?
Mobil 1 10W30 a mod?
The box says 10% hp gain, and 13%tq gain!

Not bad, only 2 HP lower than the KennBell Optimizer II Reprogram. Money well spent I think, how much was that Tuner, like $600, almost double the KenneBell. Correct me if I'm wrong here, my prices may be a bit off.

Lynn,
For real? I even thought that .alex., dynoed his, with a KB OB2flash, WITH A SHORT BELT, MORE BOLT ONS than I have, and only made like 2 more. The short belt alone has to be worth 5 at least!
Is that what you made dynoing? If I had 3.92 gears, I probably would have 2 more hp/tq with my set up.
Lynn, it was $305, shipped to my door. Less than the KB2 flash I thought. I"m still not impressed. It's not what it claims right on the box it came in!

The price is better than I thought. $305 is a better price than the KB. By abought $55, Prety close comparison for price and power. I was just trying to dig out some more info from you. I didn't Dyno my KB Opti II, but KB did and they get 10 average from it. They get more on the 5.9L, but the 4.7L is tuned pretty close from the factory. Good Luck, and I'm back in Texas Now.

Todd, I think that I'd be a bit disappointed too. Although the numbers on the box are marketing BS, I'm sure there's a note or '*' next to it.
Some of the other numbers, from other dynos showed a 13HP/25ft.lb. increase, but the starting numbers were quite a bit less. From 190/244 to 203/269.
You should be happy overall though,,, you've now eliminated all the driveline loss from the stock HP/TQ numbers :-)
I'm still waiting for my tuner to be returned from SC...........

That's
277hp at the crank
and a semi-whopping 366ft/lbs of torque!!!
That's with a conservatve 18% drive train loss.
I'm ready for one of those new taco, or frontier quads to race now!!

Todd, thanks for posting the results..lower than what I expected too..IMO.. since I didn't read you had catback or other exhaust mods, just the removed cat, you probably have a couple hp left there, but for the mods you have done, and the numbers you are putting down, that truck should be fun to drive!

Todd, one other question for you. When you said you took out the drop-in, did you remove any of the "plumbing", or just remove the filter and still pulled the air through the box, abs and ferco's?

Has anyone heard of the new Hyperpac tuner that Hypertech is making? I just saw it for the first time, wondering how it measures up to others.

joker,
I'm one who believes, that on our dodges with a nice flowing exhaust already, cat backs do nothing, except change the sound. Years ago soneone dynoed theit catback, and lost 1 hp. Going thru the same Y pipe, you could trhen split it into eight pipes if you wanted, it doesn't help. A true dual, and/or custom Y probably makes some more hp/tq. Losing the 3rd cat had to be a few, after you look at the screen it had across it.
handi,
I bought it from the group buy, posted here awhile back.
Lurk,
I just took out the drop in, and loosened the distal fernco, so I could rotate the box top upward, so it wouldn't suck the dirt and a few bugs into the intake. It was a filter, fiter/inlet removal test. I did that cause I saw people taking their filters off at the track once before a run, and wanted to see if it did anything.
I think people with death flashes, etc., mat see some more gains, some.

I just took a trip to austin and back, used over a tank of gas, 24gall tank-QC.
I USED 89 OCTANE, ON THE PERFROMANCE PROGRAM, AND NOT ONCE, DID IT PING. NO PREDETONATION, NADDA.
Seems as though the timing may not be advanced enough. I burned a whole tank of 89, so it wasn't the 93 befroe it. I thought it would ping on highway hills, I don't downshift, unless I'm passing someone, on a hill, and want to shopw off a bit. I even put my foot into going up hills on the highway, in 5th gear-not once did it ping on 89! I had the programmer with me, so when it did ping, I'd go back to the 87 setting.
Go figure, but I think there's probalby more there. I wish the give us options for the timing, how hard could that be?

i've seen other's dyno the sc on the 4.7 with less mods and also get higher gains (but totals were still ower than yours)
from what superchips says, the tuner is not meant for motors with extensive work... but kind of like an intake and muffler swap kind of thing.
that may be why your gains werent as much... because from the dyno's i have seen, yours has been the least, but you've had the most mods.

Todd, thanks for the filter clarification. I wish you were running a paper filter for the original runs, just to see if the stock air path and filter element was restrictive or not.
Also, it would be good to see the graphs. From the other dynos I've seen, the peak HP/TQ was OK, but there were better max gains at lower rpms for the TQ curve. This would make daily driving quite a bit better, which is where I spend most of my time anyway.
Also note that several others have made 1/4 runs with the SC that have shown 0.5sec gains. Half a second is a good gain for a $300 mod, and is more then a 10-15HP peak gain would account for.

good point lurkin!
what most people dont realize is when a product says "gain 15 hp", it may not always be talking about peak hp. Sometimes the gain is down in the rpm band. But 15 more hp at 2000 rpms is just as important as gaining 15 more at 5000... in my book anyway.

The numbers generated between 2000 to 3000 rpm are the ones we use for towing and work. Twenty pounds of torque down there means alot more because you use it every day. Peak only counts for racing. That torque number Todd posted of 366 ft. lbs. is in the Hemi range (379 ft. lbs.), that's good stuff, Way to go Todd!

Intense, Lurkin,
It had about the same gain, over most of the torque band, from after 3,000, and that's at wide open throttle, flooring it in 4th(manual) from 2000r's.
When do you ever floor it in 4th gear doing 2,000rpm's-I know I NEVER do.
Also, it's the entire gains under the curves throughout the rpm range. It wasn't just a short peak, it's parallel about the whole way. The torque curves from my stock, to the perf setting separate right away at 2100, with a constantly increasing separation until 3600, where it starts to fall off but stays the same gains past 4200. This describes the torque curve. You know, the torque curves peaks and slopes off, while the HP curve is still increasing.
deridge,
I haven't looked at what those Hemi's put down at the rear wheels. Maybe 305ft/lbs? Mines a 4.7, stock motor basically.

Lurkin,
Give me a call, or an e-mail, I'd be glad to show you the curves, and you could probably help me get them on here for others to see also. That'd be great!

Todd,
the dyno is only done in 4th to get your 1:1 tranny ratio... if you have more gained power at 2000 rpms in 4th, you'll have it at that same rpm in every gear.
the hemis i dyno'd with were getting around 315 rwtq... they all had stuff like aftermarket exhaust and intake
