Power mods: full custom intake, PPE headers, PPE mid-pipe, stock cat-back, E85

The pull shown on the dyno graph was done in 6th gear.
Final numbers: 468 HP / 424 TQ.
With an aftermarket axle-back, we’re likely looking at the ~480 HP range. For now, I enjoy the tone of the stock axle-back with the current set up - it keeps the car refined but still aggressive when you lean into it. Maybe down the road, if I get bored and want a little more power (and noise), we’ll bolt one on, rerun it, and retune again.

When I first drove away from the dyno shop, the car immediately felt smoother and more refined because the throttle response and drivability were noticeably improved. At the time, I didn’t fully register the performance gains, likely due to adrenaline after the session. After stepping away and driving it again a few hours later, the change was obvious. The low-end torque is noticeably stronger, and it really shows how much more the dyno tune refined things compared to the street tune we’d been running while adding mods over the past few months.

Huge, huge shoutout to Tuned by Loi. In my experience, the level of customer service, attention to detail, and overall support throughout the process was top-tier. Car runs smooth and pulls hard. You can contact him at Loi@offthelineperformance.com. Let me know if you have questions.

 

Please show the dyno run prior to the change so we can see where the gains are.

 

Unfortunately, I never did a baseline dyno stock. I didn't plan on modding it, but you know how that ends up for car guys.

 

I do have a dyno chart of an LC 500 on the exact dyno that same day. They only have an Armytrix catback on this graph. Sixth gear pull.

 

So, looks like a difference of 54 hp and 49 torque between the two? But, not exactly a comparison to true stock.

 

That's correct - that other car is not bone stock.

 

General question for all I suppose:

Has anyone dyno'd the plain old stock version that would give us a baseline?

 

The car is stock supposed to be 464 cranck Bhp, so I assume the values mentioned here are Rear wheel Bhp?

If so, the 468 BHP if really wheel HP in the first dyno is a HUGE gain compared to the probably about 410 stock wheel HP with just add-ons and a tune on a NA engine

 

Yes 468 wheel horse power. Expecting an axle back in about two months and to dial in the E85 some more. Hoping for a nice bump.
