To close several loops on my tune testing with high/low RPM launches, 14,14.5 and 15 pound boost levels i have final results for 14-pound testing.
With 14 pounds set and the data log showing 14.25 pounds on average with boost spikes, I can say for my car and mod level 14 pounds is even faster than expected.
to re-cap: I tested 15 pounds, 14.5 pounds and now 14 pounds with ::
starting IAT2 of 90f or less at start of run
170 t-stat
170 t-stat adjust in tune
3-bar
.28 gapped plugs
92-pump gas
same part of road, very near same weather and DA conditions.
I did a HIGH RPM-LAUNCH (2300rpm) datalog yesterday when the temps and humidity were similar to previous tests on my test road and have a new best time to 100mph and 105mph. At the time of the run using the datalog to calculate I found I ran 11.33 seconds to 100mph and 12.57 seconds to 105mph which is 110 millisecond better to 0-100mph than the previous 14.5 pound tune from AJP. This is outstanding for the mods, and even better considering I had +1 knock at launch. Were it not for the knock at launch I think the 0-70 would be better and would have a decent impact on reducing the time to 105 mph further.
So for those with similar SHO setups. you might consider a 14-pound test tune. I am seeing in the last two runs spark hitting 21-peak which is kind of amazing, and very high spark averages for my 2010 on the whole run due to less heat (in my head its less turbo heat/pressure, AJP comment as needed)..
I do think though were right at the limit with launching and spark for my platform. The launch and immediate +1 knock smacks of a gas issue or just a HINT too aggressive on spark in the super low rpm band. (I need to spike the gas and retest..)
But overall the experiments have pretty been damn good. shes in the fastest from she can be with the current fuel\hardware.

THANK YOU AJP!
