Shakedown -
Day 1:
Here it is, the moment of truth, DYNO DAY!
The Arizona heat is the worst of the worst case scenario. You’d be hard pressed to find testing conditions as brutal as the Summer in Arizona. It’s monsoon season, humidity is high, and today’s temp is currently at 105F and rising to a high of 112F. – Uuugh, SO HOT!
The Test Car is a 2007 2.0T FSI GTI. It’s spec’d out with our complete EJ400 Turbo Kit, a Eurojet Prototype OEM Fitment FMIC, Eurojet Turbo-back Exhaust, RS4 Injectors, Autotech HPFP, and a few other bits. If you want the complete list of mods you can check it out HERE
The Programming on the car is the Unitronic Base File Tune. It is not specific to this kit. We’ll be working with Unitronic to fine tune the kit on their engine dyno this coming week.
We can go on and on, but we’ll let the numbers of the kit speak for themselves.
Run 1: Ambient Temp – 105F with 7 Heat Range Plugs
Check out the IAT’s on the first run. The Eurojet IC is pulling the temps down to within near ambient specs. We blew the plugs once the car hit about 330WHP. So, we ran out and got a colder set of plugs and ran it again. By this time, it was pushing 112F outside.
Lesson to be learned? Don’t use NGK7 Heat Range plugs if you plan on going over 330HP in 100F+ Weather. You can see in the pic of the first dyno run where the power curve started to get all choppy and dropped off – detonation ate through plugs 1 and 4. We’d like to thank Keith at AZ Dynochips for all his help and patience as we had to use his loaner car to run to BAP and pick up some colder spark plugs.
Run 2: Ambient Temp – 112F with 8 Heat Range Plugs
Again, check out those IATs!! The FMIC is doing great in 112F weather. I can’t imagine any worse conditions to test your car in. In these desert conditions, during monsoon season with relatively high humidity, we put down 370whp and 344ft/lbs.
That’s good enough for us on a base Unitronic tune in these conditions. That’s over 430bhp!! Once tuned properly we’ll be at a smooth 400+whp on our Stage2 tune (Rods Required).


Lesson here? Lots of power is VERY addicting.

We stopped and visited some of our friends at EPIC automotive:
Day 2:
It’s hot, the monsoons are barreling in, and we need to get on the road. We’ve got 1400 miles in front of us and we need to get rolling.
We cleared the city without much of an issue. Temps were above 102 and we’re getting our money’s worth out of these tires. So grateful that the speed cameras in Phoenix have been deactivated
We hit the I-17 and shot up towards Flagstaff.
The good first half of the day was filled with rain and overcast conditions with plenty of humidity. The turbo kit did really well in the wet-drizzly conditions while making the climb from 1400ft elevation all the way up to 6000+ft elevation in Flagstaff. We couldn’t really stretch the kit’s legs because of the weekend traffic, but we found that we always had power available and could pass in 6th gear without an issue going up hills and just cruising.
We followed this guy for about 20 miles on the hike up to Flagstaff. MOVE!!!

I think that it’s time to buy a new pair of shoes Darrin.

For the sake of transparency, at times we had a bit of hesitation under partial throttle loads, but we learned how to manipulate throttle loads with your foot to smooth driving. Under 80% + throttle load, the turbo pulls real smooth and the car puts a smile on everyone’s face. The hesitation will be cured once we get the software dialed in with our specific hardware (wastegate, MAF housing, etc.) All in all, the car pulls real strong and makes its way up and down mountain roads with no problems.
Finally getting closer to Utah after about 4 hours of driving. We came to a fork in the road: Twisties or Straight-aways? We head left to the curves! Running our way through the canyons in southern Utah got the blood pumping, and we all decided the 45 MPH speed limit was more of a “suggestion.”
In case you’re wondering how the kit will run under different conditions, look no further. We shot through rain and sun, streaked through the hot and cold, and even took the car up to 8000 ft above sea level! We experienced a few minor software issues, but nothing that Unitronic can’t iron out in the final stages of tuning.
We were in no rush so we took some time to pull over pretty often, make sure everything was running well, and take some pictures. Who says a 1400 mile road trip has to be strictly business?
We stopped in Colorado City to take this pic coming into Utah. We were looking for Warren Jeff’s hotties, but didn’t find any of appropriate age. Oh well, in a few years.

Finally, the omen we had been waiting for!!! WhooooooOOOOOoooOOOooooaaaaaa!!! A Double Rainbow!!! It’s so intense! Do you know what this means!!!

Arizona down. Utah, Idaho, Montana, back through Idaho, and Washington here we come!
Day 3:
Making our way up through Utah our trip continued with a 1000 mile day. It was a loooong drive and night set in the last 6 hours or so of driving. We were prepared for the worst, but everything went off without a hitch. The only thing we were really upset about was that the bakery we wanted to eat at was closed. But we did stop at this awesome Harley Davidson dealer with a building made out of an old torn down steel factory – it was one of the cooler buildings we’ve ever seen!
What is Darrin doing to that bush?

We stopped at a few places and visited with some friends as we continued on our trek. We passed through some fun lightning storms as we approached Idaho. We continued up into Montana, swung over on I-90 and passed back through the panhandle on our way into Washington. We didn’t take a ton of pics through these parts since it was getting dark and we were all hopped up on Monster Nitrous energy drinks (Gross! Now that I think about it) and started to get a little loopy near the end of the trip…15 hours of straight driving will make you do some strange things.
Here are a few of the final details: The MFD showed an average of between 35 and 36 MPG during the entire trip. Outside temps ranged between 55 and 115 °F. For the most part we were traveling about 85 MPH. Total trip was right around 1450 miles. Driving time was about 7 hours the first day and 15 hours the second – we made a lot of stops, but we had a good time – we’re really excited with the results.
Most importantly the EJ400 Kit performed as designed. It was installed, dyno’d, and then ran across country in just a few days! There were no glitches, break-downs, or hardware failures along the way. The only issues we ran into were with a set of $30 spark plugs on the dyno!
