1 Not what was advertised
Posted by Klay on Jul 26th 2024
The tuner would not read my VIN. It only had one setting (street) and not the four that it was advertised to have. I can't even use it at all. What a colossal waste of money. They won't accept any returns on open electronics. How am I supposed to know if it works if I can't open it.

Love this tuner! Don’t believe all the negatives you read about these, call and talk to Clay if you’re nervous about purchasing one over a hydra, he’ll help you out! Can’t say enough again about all the Riff Raff Diesel folks…you folks are awesome and have a customer for life here.

This tuner does everything you need it to do. It comes with preloaded tunes which work great but if you need custom tunes it's capable of that as well. Sct is the way to go when you need tuning for your 6.0

Got the programmer before I expected. I did the update like instructions stated. Tried to program my truck and found that I got a general error code. Contacted SCT and found that older models can’t be updated. Resolved that and did the reprogram. The street tune is great for just riding around. The proformance tune is crazy on my 7.3. I did notice that it will make my clutch slip in 4th and 5th gear. Programmer it’s self is great.

Unbelievable product that really lets your truck show it self, 20 mpg urban driving on street tune while hauling butt 2000 7.3 6speed, cab and half short bed. Recommend to all POWERSTROKE owners.

I have found that Emma works great for me. I love to garden and I am most comfortable when I wear my hair up. So much cooler to work with in the summer! I have purchased more than one - one for when I'm gardening and the other when I'm out and about. It fits the bill for me!

What a classy, classic style! I am a big fan of Freedom as I now have 5 or 6 of them in different colors. I love this new Natural Grey. I love everything about this beautiful wig. She is the perfect length and color. I hope this new shade of grey remains a selection option and expands to other styles as well. Freedom is a beautiful wig!

What can I possibly say to express how I got my spirit again. My confidence to leave the house, my confidence to be seen and not feel judged for my appearance. The Freedom to once again be me and walk confidently without any doubt that I was looking my best. We all know how women feel about their hair - it is our crown and when the crown shines so do we! GSW wigs are high quality and the styles are trendy and some familiar. I am partial to the Silver Stone. It’s absolutely gorgeous and brightens my face. !

Taylor in Irish Spice is a dream come true. The colors in the blend of fibers create a gorgeous red hue and the fibers themselves are so soft and luxurious they feel like healthy human hair. As soon as I tried her on I immediately ordered a second one! Taylor has wonderful movement and looks incredibly natural on. The overall quality and the ease of care is outstanding; she washes and dries and returns to her “like new” state. The bonus is what she has done for my self esteem. I’m 73, my bio hair is white and very thin with places where you can see my scalp. I saw one too many photos of myself where I gasped in horror at how I looked. What possessed me to want long, luxurious red hair? I really don’t know! But she sure spoke to me; it was love at first sight and before I could talk myself out of it, I ordered her. Now friends are telling me I look amazing, I look 20 years younger, and I look like I should have been born a redhead the color is so natural on me. I love how I look and feel and I do think there was a mix up somewhere. I was born to be a redhead with gorgeous hair!! Thank you GSW for being an honest and wonderful company to do business with. And thank you for an amazing product at affordable prices. I love you guys!

I recently purchased Godiva’s Secret topper, Smooth Top Plus in Smoky Frost, and I couldn’t be more pleased! I have been suffering with Occipital Neuralgia and wigs have become very uncomfortable since they put pressure behind my ears, so I thought I’d try this topper, and it has been such a blessing! I can wear it all day with no discomfort, and it has enough hair to meet my needs. I’ve gotten so many compliments on how natural it looks also. Thank you for coming to my rescue Dani and Ro!

Having always worn my hair shorter I gravitate to the shorter Godiva wigs. This last order I decided to try Courtney (as that is my granddaughter’s name), in white. I have received a number of good comments so far from the family, and I too am taking a liking to Courtney. She fits my head tighter than most of my other wigs. I am a Sheila wearer as well. Have had numerous mohs surgeries on the top of my head and have a large bald spot which will always be there. I am so grateful for finally taking the plunge and becoming a member of Godiva Secret Wigs. Three of my youngest daughters were diagnosed with breast cancer, as I was also in 2017 but never had chemo, which they all had. They insisted on purchasing real hair wigs. My experience with washing and wearing Godiva Wigs has taught this 84 yr old I am much happier I chose Godivas Secret Wigs.

I received the Aria in frosted taupe a couple of weeks ago. It is absolutely perfect. I love the style and color. I wore it on vacation this past weekend and everyone complimented me. I put it on and I feel confident and beautiful.

After a year of wearing Bella top, I decided it was time to buy my first Godiva Wig. As I have a small circumference head and short forehead I was. Delighted to find that Sheila wig had all of my needs. I bought the Petite Sandy Silver short wig wig. I could barely wait for her delivery. When Sheila arrived I opened the box, shook Sheila out a bit and put her on She fit perfectly. I am so delighted with my Godiva Sheila. I am now looking to purchase my second Godiva wig. Love, love, love Sheila
