Just wanted to let everyone know that I am very happy with my Hydra EMS.

I have a 2004 USDM STi, with the following pertinent modifications:

Deadbolt TD05H-18G
Cobb Uppipe and TBE
Perrin Big MAF Short Intake
Perrin TMIC
Walbro 342 Fuel Pump
Perrin STi-Modified Injectors
Perrin Lightened Crank Pulley
Element Hydra EMS

I've been purchasing and saving up these parts over the last 6 months. I installed them recently, and the base map provided by Phil at Element had the car up and running. I did a bunch of AutoTuning, played around with my Boost settings, and the car ran well and very strong on 93 Octane gas.

To get the absolute most out of my car, I and another guy in Illinois paid to bring Phil Grabow out for custom tuning sessions. I cannot overemphasize either Phil's skill, or the Hydra's capabilities. What Phil and the Hydra were able to achieve with my car was nothing short of amazing. Boost initiation at 2100 rpm, 10 psi by 2850 rpm, full boost of 19 psi by 3500 rpm, tapering to about 16 psi at redline. The car pulls hard and smooth, and there is not a hint of detonation.

This tuning was done entirely on the street, and I do not have any dyno numbers. I have learned a great deal from this forum, and I just wanted to share my recent experience.

Thanks.....................Frank

Good to hear. What made you decide to get the crank pulley?

Yup, the Hydra is sweet and Phil really knows his system. Bump for a great tuner.

I like it.

The Hydra looks really nice, I'm glad to see it working out for people.

Did you spend any time with Phil tuning everything other than WOT?

Yep, spent time tuning general cruising conditions as well as idle.

Perrin lightened pulley seemed like a good idea, being rotating mass and all. I don't know what I gained (if anything) in HP, but the car did seem to spool faster.

You should be able to get it to hit full boost (20 PSI) at around 2800-2900 rmp 4th gear. I'm also running TD05H-18G but from FP and thats where I get full boost, but I'm running a five speed so there are some differences. I'm very happy with it. I also only road tuned the hydra on 93oct. Best ET is 12.3 and best trap is 111mph. That was with a TSX TMIC. I now have TXS FMIC but haven't tuned for it yet due to a broken tranny.

Ah! That's what I need to do !
get a couple of guys here in So Cal area to bring Phil for a tunning session.

I just recently got the last of the parts I need to install: injectors....

set up is going to be a rotated mount APS DR55 with all the other APS goodies: FMIC, 3.5" TBE, TGV deletes, fuel rails, - I may need to get an external wastegate as I've read the DR turbos surge with the internal wastegate...

Can't wait to get the STi tuned by Phil !!!
