The tune is the biggest improvement.
Your times are getting better... looks like its time for a tune update when you get the new parts.

I think we might have the first auto VT into the 13's in the making!

Stage 1.25 and your mods = 13.8 at 102 MPH (my estimation).

Eco mode is disabled on WOT, no worries there.
Boost is different during WOT with ECO mode on. There are different calculations made with ECO mode on vs off when identifying the primary commanded torque table inside the ECU. I want to say there is a time window as well (I think its 5000ms) that disables ECO mode when you go WOT.

There is a 5 to 7% reduction in boost when in ECO mode when you go WOT (differences in reduction are due to different calibration files).

Its such a small difference that it would be hard to see on a boost gauge, but inside the ECU programming it is listed.

Made 3 passes at the local strip today.

Auto trans
cone filter only
axle back removed in favor or straight pipe
tork pipe

15.6 @ 89 .8 rt
15.5 @ 92 .7 rt
15.4 @ 92 .5 rt

Left the eco mode on for all of them like an idiot...
Not bad times, considering the mods you have... it looks like they added to the advertised 1/4 mile times!
