Let me start out by saying thanks to Chris at the Dyno Edge in
Albuquerque: THANKS CHRIS!!! :)
So Chris worked over my tune today to make sure it was safe and see if
I'd eliminated some bugs from last time. Since the last tune I'd moved
the Boost-A-Pump to a more appropriate location in the wiring, yanked
the Afterburner-eFPC completely out, and added a different cold air kit
and intercooler heat exchanger.
I didn't gain anything between this tune and the last in terms of peak
power and torque but the AFR curve is smoother, the MAF curve makes
more sense, and the timing is a tad more advanced but still
conservative with 19 degrees BTDC at around 6200 rpm and peak boost at
Even though the numbers say I should have some more cushion in them it
looks like I might be out of injectors (or have some injector problems,
anyway). There's a lean tailoff that just won't go away but at least
now it's safe out there. I could beat on this tune some more and
squeeze some more torque out of it but I'd rather do some upgrades and
raise the boost level. I knew I was headed for around 18 to 20 psi
anyway I just wanted to see what I could get out of the stock stuff
Thanks a ton, Chris. You're my hero :).
I've attached the graphs, uncorrected and corrected. For giggles I
included my original baseline run which was a K&N in the stock air box
with snorkle removed and an FR500 catback.
