I've been tuned for it since January, but been daily driving it the past 3 months straight. Engine runs a lot smoother just cruising around town compared to 91 octane. The only other station in the entire state of CA that has it is in Brentwood: http://www.conservfuel.com/ I filled up once at the San Diego location...

Oh, the car was dyno'd in 3rd gear, but my tuner said the load placed on the car during the dyno run would be similar to being in 5th gear while going uphill....

The car was dyno'd on a load much heavier than what would be encountered on the street so the tune can be dialed in better. The dynapack can place a load so hard that it can lockup the axles at any speed/RPM regardless of how much power you throw at it. You are probably used to seeing dyno runs typically on a Dynojet which won't place as heavy of a load. No boost leak, you can't expect the stock turbo to hold nearly 30PSI of boost due to its design...

383whp/383 tq @30psi isn't bad on stock turbo, but I did see that the car didn't accelerate like it should. I am running a stock turbo @ 25psi with 341whp/325tq, but you have a big drop in boost pressure. you still running stock FMIC? this could help and open up your intake and exhaust more

You have a cat? That seems like that would be caused by a clogged cat... It's like you build all this boost with no change in power...

Does not seem to be working so well. The boost goes up but car does not accelerate any different.
