like i stated earlier, i'm just curious why your trq goes up and then falls flat. most the greddy tt cars coming out tuned have a pretty flat trq curve. thats where your good midrange power comes from. getting a high peak number is nice, but you'll enjoy a broader midrange better, trust me. i have the blitz sbc-id and utec with map selector. two button presses and i'm at 600whp. funny thing is i have used that setting once since the car was tuned in sept. 07. go to my350z and check some of the dynos of greddy tt cars with built motors. the numbers might vary, but the curves look the similar.

The dyno should only have a correction of 1.06 not 1.139 as I saw the other day. Then there is the arguement of this being even lower due to forced induction.
cf=1.176[(990/Pd)*((Tc+273)/298).05]-0.176
this is new SAE accepted formula to provide acurate measurements from 5 - 35 deg C
cf=1.176[(990/Pd)*((Tc+273)/298).05]-0.176

I guess the reason for the high correction ratio is that the dyno thins its @ sea level and there is a problem with the calibration that is why they used the 1.3 not 1.03

I am still noticing a major slide of torque and Hp while accelerating at the 4200 rpm mark as well as a major torque drop at the end. Are you sure this engine isn't suffering from detonation might really want to ask your tuner.
I also noticed that you had 149 dyno runs on this car. Is that safe to do? Or is that the total number of dyno runs on that dyno? Is this like a brand new shop?
Keep up the good work and keep the big numbers coming.

I dunno where he got his 1.06 figure.... Red Deer is 3000 feet, minimum correction for altitude alone on a perfect day would be 12%... doing the math by J1349 you get 13.2% correction.... using J1995 you get 13.9 ... I dunno what j1339 is, but between his formula and J1349, there is no difference in the final number.
If on some of the pics he saw the pressure, it's probably wrong.... the DynoDynamics weather station was ****ed... read 31 in Hg and would not change... we used my portable weather station I carry with me... (AROUND 890 mB as I recall) Fidel sent his unit back to DD.
In reality, NONE of the corrections are really approved for correction above 1.07, but its the best we have, but for higher elevation, it seems the correction should be skewed upwards anyway... ie, the NHRA accepted factor for correcting ET and MPH in Calgary (almost exactly the same elevation as Red Deer) is .9565... you work the power numbers from that, and you get about 14.4% on a good day .... so its all in the ballpark, all the factors, formulas etc were derived through empirical testing, and regression analysis.... none are an "absolute".
BUT
There really is no good correction factor for boosted cars.... the correction would have to be boost referenced AND turbo efficiency referenced, and vary depending if you were running wastegate spring pressure, or manifold absolute pressure targets for boost.........
so, pretty well everyone in Alberta just uses the same correction for a turbo car versus a supercharged car, nitrous car, NA car.... the reason is because the power numbers are most relevant here..... compared to say a same weight car with the same NA hp, the performance will be the same.... so, if a guy showed up with a 544 na power car, you would run the same as him HERE. Had there been no correction used, your number would be much lower, but you would still be the same speed.
As for the AF ratio's.... we made a bunch of runs.... that just happened to be where that particular run was... Fidel probably has numerous tunes at different boost levels, I think he just left the best one for the boost the car was left with.... we could not make one tune for all boost levels at the time cause the areas in the base fuel table the ecu looked at at various boost levels were the same... with overlapping MAF values at various rpms across different boost levels..... changing it for one boost level, changed the AF for other levels....
The dip was where the boost "rippled".... if you look at the higher boost logs, the boost curve was never exactly the same down there, and this affected the AF ratio at that point on occasion. .... I dont think this was in your final graph, I think the curve was flatter, but you would have to check with Fidel.
Did I get everything ? lol
