"Full Bolt on" Dyno
Max power = 345.54 - Max torque = 352.35 - SAE smoothing = 5 - A/F was between 12.73 and 13.00 whole run.
Supposidly the dyno was jipping everyone about 10 hp/tq from what everyone was saying, even so, im satisfyed.
Last dyno was just lid, catback and p&p throttle body which = 313/326. So i believe it jipped me just a bit as ive added ls6 intake and pacesetter longtubes, 3in. ORY and ASP U/D pulley. Then agian this is all through a 9" with 3.70 gears

And did you ask the dyno operator about this?
We ran 4 cars that I previously tuned. 3 outta 4 ran the exact numbers as when they were tuned. The one that didnt had some KR. As did yours.
If you want to call me I can tell you whats up. I can also email you a graph thats alot easier to use for posting on the 'net, if you've got photobucket of similar.

I dyno'd 303n/a on a dyno in my town, went to OKC and dyno'd at 296n/a so, there are some factors and then there are dyno's that just read lower
The point I was trying to make is there is alot more reasons for not putting down the power you expect than blaming the dyno. How about 8 degrees of KR through the entire pull.
Usually a stingy dyno will not be off a set amount. It a % thing. If its off 1 or 2 percent, then the difference will be greater the higher the power output of the car.

Yesterday I ran 4 cars I had previously tuned. 3 out of 4 ran exactly what they ran when I was done tuning them. A couple of them months ago.
The GTO with the maggie, 532 yesterday, 531 2 weeks ago.
07 C6, 378 yesterday, 378 two months ago.
C5 H/C, 424 yesterday, 424 MONTHS ago.
The one that didnt had some KR.
Theres things you can do in a tune to assure a car will make repeatable numbers. I know these cars were tuned on my dyno, but I can guarantee if they go to another DJ they will be real close.
Dont want to name names, or throw anyone under the bus, but you need to get with your tuner and get it straightened out. Theres no reason for 8 deg of KR thru the whole run.
And BTW, stay safe on your deployment.

Thanks for the tune and the dyno day.

I was able to break 346rwhp thru a 12bolt n 3.73s. Only lid n longtubes with the ls1 intake....
