Awesome experience! Hill, Jeremy, everyone at Agile are great to work with.

We added colder plugs, Cobb SF intake and Prodrive boost solenoid (EBS). Rest of car was straight Cobb 93 octane Stage II when we rolled in, Cobb downpipe & TBE.

50 ft/lb gain from 289.9 to 340.0. 75 hp gain from 253.9 to 328.5. VERY HAPPY with results! Smooth power band, peak torque raised from 3,300 RPM to 4,200 rpm. I wanted to retain low end grunt and I am good with these results. The car pulls like crazy between 4,000 - 6,000 RPM now. Peak HP RPM at 5,600 is only 200 rpm higher than before and starts incrementally climbing over baseline starting at 3,200 rpm. The car backfires less than before, AFR 13.04 compared to 13.33 baseline.

The Cobb SF Intake (black powder coated with blueish filter) looks good and makes lots of new noises. Still getting used to it. Wooshy blow-off types of sounds, can hear turbo whine a lot more. The Prodrive EBS holds boost and I don't know if it's the tune or solenoid or a combination but it spools up faster (boost needle climbs much faster) and holds 19.4 lbs boost longer over the rev range. Both TQ and HP curves are much smoother than Cobb Stage II 93 octane off the shelf map.

Many kudos to Hill and his team. They answered all my questions and it was a great experience! I would reccomend Agile to anyone who wants a good tune!

Which mode did you install your Prodrive solenoid in; bleed or interrupt?

[Sti491]

Geeze, not really sure. Next time I talk to Hill I'll ask. Two of the lines are attached ... one to the wastegate actuater (I think) the other to the manifold. The last one is vented.... so maybe that means "bleed"?

I've read about this before but forgot to ask during install. I'll post a pic of it when I'm on my other PC.

Can't tell you how much fun the car is to drive now. So sooooth and partial throttle roll ons 1st- 3rd around town are just amazing.
