| Since myself and StormS live in the same state and I did mine in Nov time frame. This would be something to look at. My Stg V+ on 15psi ( stock timing ) just push pedal and go. Conditions 
Chart reading from left to right is: RPM's, Measured TQ, Measured Hp then Corrected TQ, Corrected Hp then number of seconds it took to gain the power from start. 
Final number peaks and Avg.'s Shop and Dyno operator said my RWHP numbers where so low because the car was running so rich and I need to get an adjuster. I ran a O2 senors in the exhaust pipe, which showed the car was not buring all the fuel coming out the exhaust at WOT. 
Dyno of mine and a 280zx with some mods below. Light blue is my RWTQ and the 280 dark blue is RWHP. The 376.5 is RWTQ at my highest Hp reading. 
Ok, two days later came back to run 17psi. Same conditions weather wise and car parts, just 2 psi more. What I soon realized was the plugs where fouling out on the top end and bad. Power would drop drastically. Plus I should have pulled them and cleaned them too before hand. This is Max Measured RWHP 392.7 
Max RWTQ 451.3 
Again RPM's, Mess RWTQ, Mess RWHP then Corrected RWHP, Corrected RWHP and seconds it took to get that power from start. Yes, that's 400 corrected RWTQ at 3600rpm's in 3.48 seconds in this old 1991 motor w/ 92k miles. I got the car 5 years ago stock with 72k miles on it. 
Forget the 15% numbers, There not right, but here's Peaks and Avg. of that run. 
Stock turbo's, Stock timing, stock injectors, stock intercoolers, stock cooling system ( at the time ). No fuel adjustments. Out in the parking lot when we did the Dyno with our Z club and Seattle Z club 
Here's some of those Z's from Our Club, Seattle club and Vancouver, BC guys ( see mine ? )
