So a little update with some HPTuners Porn for you guys...
(Bear with me, Im still new to the Software)

Looks like with the Current set up:
JLT Intake
Kong 108mm TB
VMP 105MM TB Adapter Plate
VMP Apex Pred Lid
VMP Apex Street Core
VMP High Flow Water Manifold
170oF TStat.
ID1300s
2.6 Grip Tech Upper Pulley
SPE Adjustable Aux Pulley
NGK 6510 Plugs gapped to .027
Kooks Long Tube Headers
LTH Res Delete

I'm seeing between 14-18PSI boost. I'm pretty sure with a 2.6 I should be seeing 20-21ish...

Im gonna swap the belt first, see what impact that has, then if necessary, consider upgrading the Tensioner.

Upon Further Review....

Looking at the info with my tiny retard brain... I don't think this is belt slip... I think Slapping it on the dyno in Southern Florida in the middle of summer on 93 Octane is raping my face above 7200RPMs....

Apparently 20-21PSI on a 2.6 isn't the norm... 2.6 usually sits around this boost level. (If someone can make a correction to that I'm all ears.)

anyhow, it looks to me that timing is getting pulled up top causing the dip in HP.

I'm thinking an E85 tune would be TITS with this set up.

E85 is the TITS with every set up. DO IT.

When I did these modes my thought process was “what can I do that will be able to run 93 AND E85/Race fuel without making major modifications?”

I think I’m there pre blower port or swap… I’d love to be able to ride around town on a 2.6 at 93… flip to E85 for the track and let her rip. Gonna pull the trigger just need to find the time to do it.

Do you flex fuel or do you have to run multiple tunes?

Flex fuel on LS is the shizznit. +$200 for the sensor and I can throw anything I want in the tank.

Little update: Ordered up some Boostane. Gonna try some more pulls when I get a chance and possibly get her down the track in the next few weeks.

Big thanks to @Justin@VMP for taking a look at the logs and dropping some expert knowledge on me.

Still waiting on that 3100 TVS!
