New Cam-only LS3 dyno results:: 517whp/462wtq 24* timing I don't post on LS1tech very much. I'm normally on the corvette forums, but I wanted to share this information.
My name is Justinjor on the Corvette forums.
After going back and forth on the possibility of adding another bolt-on to the car to break the 500whp mark, I finally pulled the trigger and boy, did it pay off.
With the only addition being a Bare Essentials Racing Ported LS3 intake manifold and a retune, the car picked up 24whp and 18wtq.
Previous best was 493whp and 444wtq after the cam was installed last November.
As you can see in the dyno overlays the fueling was nearly identical in the 2 passes and the entire dyno graph was essentially shifted upwards.
No dyno tricks, no gimmicks
Mod list
Halltech SBMF103
OBX 1 7/8" headers with catless 2.5" x-pipe to stock NPP mufflers
EPS 230/238 .600/.615
BER Ported LS3 intake manifold
CNC Ported throttle body
25% UDP
TR6 plugs
Here is the background story that I feel is most important to share.
I have purchased from Cajun@BER in the past and have always received top notch customer service. Anyone who knows him, also knows he provides a 100% satisfaction guarantee on any parts he sells. Being the pessimistic type, I was hesitant to buy a ported intake manifold against the recommendation of a few very reputable people. "It wont make power, you're good where you are" are a few of the responses I received.
Well, being the stubborn *** that I am, I couldn't leave well enough alone and I wanted so badly to make over 500whp cam-only so the order was placed with Cajun while the manifold was on sale about 2 weeks ago.
The manifold showed up in the middle of the week and I had it installed the same night and I hit the dyno 2 days following.
After a few pulls on the dyno, the car made 499whp and 433wtq, a gain of 6whp, but a LOSS of 11wtq.
Needless to say, I left the dyno very disappointed and I placed an email with Cajun the next morning. My first inclination was to remove the manifold and get ready to ship it back for a refund. At that point, I had spent $30 for dyno time and would have spent another $15 for shipping, but I would have at least tried it out to see how it performed.
This is where things start to get REALLY interesting.
Cajun promptly(as always) emailed me back, very concerned with the news of the cars lack of performance and unbeknownst to me, had forwarded the results onto the BER tuner, Brett.
Within a few hours, I had an email from Brett asking if I could make some adjustments to the tune in order to really get the manifold dialed in. I didn't realize how ignorant I was in the fact that the car needed a touch-up tune to really see results. I just thought I could bolt it on and see more power. Boy was I wrong.
Over the course of a week, Brett and I exchanged literally over a hundred emails about the tune, how to fix it, what it needed, what I could do to make adjustments--he basically taught me a beginners, and then advanced tuning course over the entire week, all without the hint of frustration and without ever seeing the tune. WHO DOES THAT?? He also went out of his way to give me his personal cell phone number so we could exchange texts and voice calls, to further dial in the car and get the fueling/timing right where it needed to be. I would go do some 3rd gear street pulls late at night, log the results, type them out and email them, and he would ask me to make adjustments. Brett uses EFI Live and I had HPTuners so he had to rely on my screenshots and verbal or written interpretation of the log results to make adjustments. He never had my tune in front of him and never had my logs, and he was still able to nail down the tune and intelligently communicate it to me so I could adjust the tune myself. Brett is a rockstar and I can't thank him enough
Never in my life have I had someone take so much of their own free time to help me out and be so passionate about something, expecting absolutely nothing in return. I salute you sir :salute:
Armed with my new tuning knowledge, and with the assistance of a local friend and LS guru, Chris Weber, I went to the dyno this morning to get the car dialed in. The results speak for themselves.
I could not have done this without the assistance of a great local friend, and the watchful guidance of Brett. I have the tune and the logs from the passes and the timing was 24* at peak, and a solid 12.4-12.6 air fuel.
Brett, Cajun, you guys are world-class and your attitude and customer service speaks VOLUMES for your character. I applaud you both, and only wish I lived closer so I could take you out for a beer or 3.
I can't thank you enough for all the extra time and hours that were put into this seemingly minor modification. The fact that you went so far above and beyond to help me, leaves me speechless. Thank you so much gentlemen :woohoo:
Now, I only wish I had 1 more day of winter to take this thing to the track and have a timeslip to backup the dyno results. My current best pre-manifold and BER tune is still 10.7@128 and is currently the fastest cam-only LS3 on the Corvette Forum.
Thank you again

No problem Justin. It was great dealing with you and I am just glad that it all worked out in the end. Every second on the phone and typing were worth it. You deserve a lot of credit yourself. You took all you could from me and made it happen. Most poeple would not have taken the time to actually figure out the issue and just bashed the product. So cudo's to you and I hope you are happy with the results. Now take that top spot on the drag list and all goals will have been met. Let me know if you need anything else.

Oops, I didn't have notifications set for this thread.
Pat, thanks for the great cam choice. I know they're boat motor lobes but damnit, they work very well.
LSA on the cam is a 113+2.
Thanks everyone for the comments.
The car went a new personal best of 10.67@129.2 on a 1.48 60ft last weekend at PBIR. The weather wasn't the best though with 78*, 50% humidity and a 30 barometer.
DA was +1000 for my pass.
