Hello everyone, once again Terri and I wish everybody the best and we hope you are all staying safe

We totally understand that times are tough for many people, we have been extremely fortunate to be still shipping a lot of modules to folks who are installing them themselves or having their personal mechanic install them.

We have upgraded cars obviously throughout the United States and Canada but also several in France, Belgium, Germany, and Panama. With over 100 testimonials from the fine folks who trusted us upgrading their car, which are all posted on my website, occasionally I get a few that really catch my eye. I just wanted to share a couple with you.

Hi Jim,

You’ve overwhelmed me with This MRC unit. I have changed/customized/replaced so many parts of my c6 ZR1. This is the best improvement I have done, and it’s not even close. I noticed the massive difference as soon as I got on the highway. If I listed the modifications, I have done it would look like the credits in a movie.

Again, unbelievable! I love the new super sport! How do you do it? It’s a completely new car. Blown away, just blown away.

What I’d like to do, is send you my original core, have you sign it, and send you back the core I purchased. I’m willing to pay for both.



Hi Jim,

I now had some time and taken the car on several longer road trips. I’m very impressed with the upgrade, its almost like getting a new car. Its a lot more confidence inspiring on bad and bumpy roads and for the first time I now use the sport mode on ordinary roads as well.

I’m happy that I didn’t change my tires before testing this, I was going to go with Non-runflats next time to “soften” up the ride a little but now I think I will stick to the stock setup.

Also, we have been truly fortunate and honored to have several of these Corvette owners post in the Corvette forum. The Corvette Forum has more members than any other forum in the world pertaining to Corvettes.

I just wanted to take an opportunity to share these threads.

Again, I just wanted to thank each and every one who has allowed us the honor to upgrade a car that I know is so precious to them.

Thank you, Jim


Last year I purchased a C6 Grand Sport convertible.  I bought the car in Texas and drove it back to Michigan.  In the fall of 2018, Jim asked if he could upgrade my car to get my thoughts. The transformation is unbelievable! The pleasure of driving the car in either tour or sport can’t be understated.  On my drive back from Texas I never put it in sport.  Now I do almost all my driving in sport. If I just want a nice cruising car, tour is perfect.  In both tour and sport, the car just glides over the bumps that used to beat me up bad.  Also, I noticed how much better the steering is, which surprised me.  Now I can’t imagine driving the car without the new programs.

After a total of 10 hours of seat time.  In both tour and sport. Mix of freeway 55-90mph with hours rural backroad and small-town slow driving. I like this new cal so much. Both tour and sport absorb the bumps very very nicely and are still stable and composed.  Everyone will notice a considerable difference. Read More Testimonials ->

Jim come to my house to put the calibration in my 2010 ZR1. When I bought the car, I had to drive it back from Texas to Michigan. 18 hours on the road was a bit of a headache. The car was a blast except for hitting potholes, railroad tracks, and impacts in general. Since the calibration, my car drives and handles 100x better. The impacts seem to be non-existent. Going over railroad tracks are a breeze and the sport mode is a true sport mode now. I’m amazed every time I take out my car. Love every bit of my new calibration. Read More Testimonials ->

Josh H, 2010 ZR1

The ride and handling for both modes is a dramatic improvement. As soon as I left Jim’s house in tour mode, I instantly felt a more “modern” feel to the car. Very comfortable now and yet more the handling is more responsive. I do not feel the hard rebound over larger bumps. It doesn’t pound my dash when I go over railroad tracks like it used to. I feel that there is more steering response at lower speeds and of course at high speeds.

When I put it into sport mode, I feel a good difference. Now I feel a nice transition between tour to sport. Before the upgrade, I never put it in sport unless I was showing my friends how harsh it was. I am driving it in sport mode more often now. The ride is so much better as well as the cornering.  I want to say it feels like a new stab bars were installed. It’s that much more balanced through the corners. Read More Testimonials ->

Blake L, 2009 ZR1

Just wanted to let you know how happy I am with the driving improvement. Drove over 250 miles yesterday. I am no expert but would say the car feels much more stable, planted, kind of hard to describe but driving over rough pavement sections has a sense that the suspension is working much more refined. These are really nice cars and your program just adds to the experience. Read More Testimonials ->

Galen C, 2012 Grand Sport

On a regular basis, I’m on roads with rough, heavily-worn asphalt, pot holes, sections of cracked and broken-up pavement and fragmented road edges. For around-town driving, I have MR set in the “Tour” mode and with Jim’s MR cal the car gets over all those crappy road surfaces with a bit more comfortable ride. On roads which are in better condition, but with bumps and heaves, the ride seems more controlled.

When hammering my ZO6 through the twisties in the mountains near my home–State Route 33 from Oaji, California over to where joins with SR166 is a favorite of mine–I put MR in “Sport” mode. With the Mero-calibrated “Sport”, when driving over high-frequency, low-amplitude chatter bumps, ripples, cracked pavement and stuff like that, I don’t feel those disturbances quite as much. Also, Sport, with a Mero MR cal, seems more appropriately-damped in that kind of driving than did Sport with the stock MR cal. Lastly, the car’s response to steering input, especially in an autocross movement or an emergency evasive maneuver seems different. The best way I can describe this situation is that steering is more “crisp”–for lack of a better word.

In short, I was impressed with Jim Mero’s C6 MagnaRide calibration, not only because of the improvements discussed above, but because his stuff is for “real world” driving and not specific to track use. Read More Testimonials ->
