  1. Just as described. 5 Star Review

    Posted by on 17th Jan 2017

    Customer service was excellent. Van, the oenergy, talked to me for at least 20 minutes before I purchased the tuner. It was delivered on time just like he said it would be. The Lund tune was excellent. My car with a JLT cai, pypes off road x-pipe, and an unrevised Lund 93 tune made 403 rwhp on a dyno jet in SAE. I can't say enough about this company. I will buy from them again.

  2. great tuner and very user intuitive. 5 Star Review

    Posted by on 28th Nov 2016

    This tuner is easy to use and very user intuitive. Follow the basic instructions and enjoy being able to change and control many aspects of the way the car runs and drives. The ability to adjust for gears and tire sizes alone makes this thing a no brainerfor me.

    The 91 octane John Lund tune for my car runs and drives better than the custom 93 tune the first owner had installed. I have yet to dyno, however it is smoother, faster reving and seems to make more usable power everywhere.

  7. SCT X3 Custom Tune 5 Star Review

    Posted by on 14th May 2013

    Wow! I was missing allot from not having my 2011 Shelby GT500 custom tuned. The car is night and day from what it was. This is the way it should come from the Factory. Van and Jon Lund have quite a reputation on the GT500 forums for being quite knowledgeable about custom tuning the GT500s, there the best at what they do, I was sold. I'm still messing around with more Mods and Van and Jon are just email away to get any changes to your Tune. I'm very happy and look forward to doing business with them. You won't be disappointed.

  8. SCT and Lund tune...Awesome for GT500 5 Star Review

    Posted by on 22nd Apr 2013

    I had a predator tune installed and while the performance was good, it started to give odd real-time feed results. Van at Revan was there and answered all of my questions. Ordered the replacement tune and the order was processed on a Sunday -- which is fantastic. Anyway a fast ship, no issue load and I am one happy customer.

  9. sct and jlt equals win! 5 Star Review

    Posted by on 26th Feb 2013

    Great combo. I was looking for a nice boost in performance and it delivered with noticeable acceleration, lots of torque, the throttle response was exceptional. The tuner was at my door step 5 days later (3 business) and the install was simple and flawless. Thanks revanracing! Can't wait to see what's next.

  10. SCT, Balancer, Belt, Throttle Body 5 Star Review

    Posted by on 23rd Feb 2013

    I have 2009 shelby GT500. I have contacted several tuners, bud Mr. Van was the only one who replied very quickly and gave me very good advice. I bought SCT, 10% OD Blancer with HD belt and Throttle body. Everything is the best quality and was shipped very quickly. Now I need to buy several more parts and I will assembly all together and write how many HP it gave me. I want to thank Mr. Van and all team of Revan Racing and highly Recomend this company to everybody.

  11. SCT tuner for my 2011 GT500 5 Star Review

    Posted by on 26th Dec 2012

    I purchased my 2011 Shelby with 908 miles on it. As the 2nd owner I inherited a few great mods, installed by Van (Revan racing). One of which was a 2.6”pulley which required the vehicle be tuned. As it turned out the tune was personally done at the track by Jon, so I did not receive a tuner with the car. Also I discovered once I relocate to Idaho, emissions testing is thru the OBDII port, and it’s not uncommon for the rear O2 sensors to be disabled on performance tunes. And to top it off, 91 octane is the norm. So I emailed Van several times with questions, and each time Van responded same day or next day. I decided to order a tuner, to include having all emission triggers enabled, and both a 91 and 93 octane tune. I received the tuner within a week, uploaded the existing tune and dropped in the 93 tune. I haven’t had a chance to take the car out, just started her up, but I have no concerns the car will run same as before with no performance loss.

    Also, the site was very easy to drop in the needed info for purchase. I received a tracking email which again was easy to use, and lastly a review email hot link, quick and easy.

    I highly recommend Van and Revan Racing as a go to Mustang source!
