GT350 Dyno Tune - JPC Racing/HP Tuners

Aaron@Jpcracing · Jan 20, 2016

Just finished up doing a dyno tune on a customers car using HP Tuners today. Car came in making 498rwhp on our dyno and 408ftlbs of torque.

With our tune the car threw down 514rwhp and 425ftlbs of torque. Total gains of 16rwhp and 17ftlbs of torque. Most of the torque gains were found in the mid range.

Car was 100% stock other then the tune.

Red line is before, blue line is after.

While currently were not offering email tunes. We will be offering tuning in house.

Super happy dyno, but I like what they've done with it. They gave it a nice boost in the low end and smoothed out the torque bump very nicely. There's also a good increase in the top end where the stock tune starts to fall off.

I like how they got rid of the plateau at 2500.

There were alot of gains found in just the cam timing alone. Let me know if you guys have any questions

Was rev limit extended?

If you guys start remote tuning by the time I get mine, I'll have to get in touch. Is there a possibility of Flex Fuel tunes in the future with the HP Tuner software, or are you sticking to separate E85 and 93 octane tunes?

Do you guys have any guesses as to why there is that plateau/dip starting at 2500 until the torque really kicks in around 35000? Emissions, maybe?

Look up dynos for other FPC engines (F360, F430, 458, etc) and you'll notice a trend ;)

Nice work with the tuning.

Living in California with 91 octane I wouldn't consider anything but a Flex Fuel tune. I hope to start hearing some customer feedback on the forums since Lund announced their's more than a month ago.

Very interesting. I never noticed that. Most of those dyno graphs look like mountain ranges. Is that because of tuning for the track or because of the characteristics of a FPC engine?

I said it once before on here somewhere, but Ford did a great job tuning this engine for a flat torque curve. If anyone feels that they didn't, just look at a Lamborghini Huracan dyno. The second picture is even after a tune!

[MENTION=16436]Aaron@Jpcracing[/MENTION] same question as above and I'm also thinking emissions compliance?

Wondering if this is anyone's gt350 on this site? The dyno definitely reads high and only the delta should matter but I'd be curious to see if it's also been tested elsewhere.

Well I'm not saying they didn't but it's just a curiosity.

I wasn't taking a dig at you. I just wanted to show how the FPC dynos typically look, and point out that Ford actually did a pretty good job on their OEM tuning. The Huracan is the most interesting to compare to me because it's also 5.2 displacement.

Interesting. I'd further your compliments to Ford....The Huracan had less challenging constraints - packaging the motor (pure sports car vs every day car with trunks etc), budget, and mass production. :ford:

The huracan runs 12.7:1 CR. Maybe more to squeeze out on the GT350 there...maybe not. Im not an engineer.
