GIAC S2 on Mainline DynoLog.

Just had my S2 flash installed but this time it was dynoed on a Mainline Dynolog.
Mods are: AMS fmic, EAS DCI+scoops, UR cattless DP's
Final results were
S2 pump tune: 386.1whp
S1 tune: 329.9whp

Previously when I had my S1 installed (same workshop) they ran a Dyno Dynamic dyno.
Mods back then were only UR cattless DP's
Final results were
S1 tune: 302.4whp
Baseline: 254.1whp

My problem is I don't have a baseline on the Mainline Dynolog.

Now here comes my question?

1) Do Mainline Dynolog read higher (Anyone have any dyno time on these)?

2) Extra supporting mods and tune made such an increase in power?

It took 4hrs to install the map due to communication errors and incorrect maps loading. But overall I'm extremely pleased with the GIAC S2 tune, well worth the wait!!!

The results are exactly what GIAC advertises. The intercooler definitely increases power at those boost levels.

So close to 400whp
