If we compare the numbers, yes we do look at peak, but we like to see the truck to make gobs more HP and torque across the entire RPM band, from launch to max RPM, or the area "under the curve".
Regardless of where you measure, 4K, 4100, 4500, 4900 ect. it is making more HP and torque.

Although I dont have the Heads and Cams, (and the extra power that comes with it), man I got to tell you, having over 20 lbs of Boost (in which @18 lbs is immediate upon stabing it) is just absolute tire ripping fun on the road. Massive low end power and torque I truly cant use most of it on the streets, I dont know how you guys with all the extra power do it.

ALTHOUGH I WOULDN'T MIND HAVING THAT PROBLEM TOO ; o )

My A/F's been fixed since this Dyno (new pumps and exhaust changes)



The important #'s are coming tomorrow night if all goes well.....

Good luck with the 150 shot tommorrow Rob, I am currently using a 100 shot with a small amount of timing. A little afraid to bump the timing since I lost my last motor to nitrous. You should crack the 600/700 hurdle. Good luck again.

Rob-

How much overall timing in the tune that laid down those numbers?

Thats with pump gas i assume.

 

Thanks Rich

Schitt I feel slow with all these BEAST around here these days

Torqy,
Yes thats a 16 degree "pump gas" street program. I have the SCT Multi-Chip but thats the only Program I've used so far. "It's a work of art", we street tuned it, Dyno tuned it, data logged it, I got tweaks for Shift Points, Down Shifts, OD in and out, Torque Converter Lock Up, Tip in, Torque Reduction, Limiter, etc. After the new Bigger Fuel Pumps and Catback it put out a flat line A/F of 11.8 from start to finish, "as if you used a ruler" WOO HOO....

We'll make up a more aggresive gasoline Program (even know I'll never use it), and a lower timing N20 program, (maybe two?)

I CAN'T WAIT to Spray

 

I like seeing 11.8 AFR. Our motto has always been "safety first". We generally keep the AFR around 11.5 to 11.8. It has worked extremely well.

The tuner I used shot for 11.4 across the board. Probably could of had it leaned out alitttle. Just nervous with the motor after seeing what damage a leaned out motor does!

fastspec- you think my numbers are on track with everyone else. My nitrous tune could be adjusted, what do you think?

Rich

 

One thing we noticed in all our tunes, that depending on time of day (temperature) and how many previous runs had been made, the numbers would vary quite a bit. On yours, I would like to know when the runs were made, engine temp, previous (if any) runs etc.

That way I can truly compare "apples to apples".

About a month ago, we had 11 L's visit us for a Dyno day. Many different combinations. Some stock Eatons, ported Eatons, Magnum Powers cases, Stage 2 JDM's etc. 1 Johnny Lightning stage 2. I still need to complete my matrix of the various combinations, and the power each one made.

Here is a picture of the line up that day:
