Tuned? Have dyno graph pre/post?

[Fifty]

it seems that I can't get any of the tuners in the gmc world to post up pre and post curves as well as afr graphs....

Seems kind of silly... I'd like to know that they aren't squeezing the tq by running super lean on 91...

Also different tuners run different ways to get power, timing vs fuel vs cam timing etc. I'm interested in a nice early flat bump instead of a peak bump. Would be nice to see who can do what instead of just the whole "trust me"...

Anyone with graphs like to post up. Include yr, fuel, mod list and tuner (with dyno type used) if possible!

AFR is irrelevant. Leaning the mixture does NOT make more power. That is a common misconception. Power output is relatively comparable from 11.5-13:1 and falls outside of that range.

Timing is where power is made as long as fuel is in that acceptable range. Anybody with the "lean is mean" mindset shouldn't be touching a tune.

K&N Dyno charts. Took all of 10 seconds to find it..

Jeez, kids these days.

Afr is king...which is why I was looking for a documentation. I agree, people
Going "lean is mean" as you put it should be shot...

For instance on my land speed car, I paid a lot of money for a gentleman to retune for a few minor tweaks and he wanted to show how much power he could squeeze...went really lean on it...luckily it runs E85 and was cool enough nothing broke on shake down runs on the rollers...

He was replaced...but wouldn't have known how dangerous tune was with out the graph....well until it popped...

Ezdarr...is k&n offering tuning services??? I didn't think so.

Also,
Jenna bear, I would never ask for timing tables, as that is proprietary info...

Just before and after results and afr rates...DAM too, but nobody ever graphs those...plus that's a pretty day by day event that would just have to be monitored or logged if it gets crazy

I haven't found many in my search either. But Livernois is one..

uh oo.. they use a low temp thermostat.

 

[JennaBear]

My thoughts exactly....

Yeah...
Kudos for posting their graphs though... Not to hip on the need to for thermal band aids to cure a limited dial in of the fuel and spark maps...
