John brought his FlexFuel EvoX MR over from Pensacola to get dialed in for some more boost at Stage 6 Motorsports after changing his MAP sensor over to an Omni 4 bar. This car has an Extreme Turbo Systems GTX3576 turbo kit with the boost touching 40psi on E85 (tapering to 31psi from back pressure), and 25psi on 93 octane. The fuel system is a Radium Engineering fuel system with twin 255, lines, and a fuel rail that has some Fuel Injector Clinic 1650s in it. The 2.2L engine and transmission came from our friends over at Kozmic Motorsports when the build was done a few years ago… still running stronger than ever!

As always, it was a pleasure to tune yet another car from the far end of the state 🙏.

Sometimes the gimmicks just absolutely destroy the efficiency of your engine. This 370z is a great example. Originally it was brought in for an intake manifold spacer, and a Takeda intake installation (along with injectors and a fuel pump to support E85). The car already had some throttle body spacers with some weird funneling machined on the inside to swirl the air. Unfortunately, after the installs were done, and I got on the laptop, the car was severely underpowered.

Post tune, the owner and I discussed what was holding it back with quite a few options… the intake spacer, the intakes because they neck down at the MAFs, and potentially the fabricated intake manifold, but I wasn’t 100% on the manifold because it looked like it should work.

The owner brought the car back with a ported intake manifold from Z1, 3” intakes from Z1, and a flexfuel sensor kit to make the tune a little more consistent between fuels. During the installation, I removed all the spacers.

Making power naturally aspirated is always a challenge. The package really needs to breathe efficiently, and the gains aren’t really there from changing parts here and there. Well that changed with the newly installed parts! I am still kind of shocked to see the car picked up 43 horsepower over the previous session on E85.
😳. Thankfully the owner is really satisfied with making 350hp in his auto transmission 370z

Hey friends… this is NOT how you drop your car off for a tune. I know times suck with these gas prices, but if you are doing a single fuel tune, bring it full, please.

Since we don’t have a heater, this is how we have to warm the shop up 🥴

Christine’s STi at Dirty Racing Products for some goodies and a flexfuel tune. At the heart of this update is an Extreme Turbo Systems turbokit with a GTX3584. This car has a stock engine still, so the boost was set to 24psi on ethanol, and 20psi on pump gas. A Radium Engineering fuel pump hanger was installed along with a relay kit to ensure we had all the fuel supply we needed to keep the Injector Dynamics 1700s operating smoothly.

The best part about this update was getting this car on a Haltech Nexus S3 package from our friends at Dialed In Motorsports. The car tuned so smoothly, and runs flawlessly with all the needed failsafes such as oil pressure, fuel pressure, boost limits, and air/fuel ratio.
