Highly recommend Garrett Tuning to anyone looking for a base tune or performance tune. I recently upgraded my camshaft and had my Silverados idle tuned by Brad. He was very thorough when it came to tuning my vehicle and charged me an extremely reasonable price. The men at Garrett Tuning are extremely professional and knowledgeable and are willing to work with the customer, which is why Ill be returning to Garrett tuning for all my engine performance tuning needs.

Very happy with my experience with Garret Tuning. Would recommend to anyone, especially if you have a ford with the Pats security.

Prompt replies via initial emails. Contacted me directly to discuss concerns via phone. Straight forward conversation. Shipped replacement ECM very promptly. Provided proper tune needed and customer is very happy with results. Recommend to anyone doing a basis tune after some modifications like my customer had. Will do business with again

These guys are AWESOME!! I have used Flagship 1, AND All Computer Resources. Garrett is the ONLY one that didnt leave me hanging. Check out the BBB scores. They are rated VERY high. Thanks you guys. Its a shame that when doing a Google search, the companies that provided poor service always pop up first. Garret is the BEST, but I had to go digging to find them. Thanks you guys. Wish I would have found you first, and saved myself all the disappointment of working with other places that pale in comparison. Youre the BEST!!

These people bent over backwards trying to get me a tuned fuel control module for my 2007 silverado. gm couldnt even do what I asked, do to not having the corresponding program for my vin and having not so helpful technicians. These guys new exactly what gm did wrong solved the problem built a module off years of stored data they had . they were proffessional and very responsive to my phone calls and questions. They definitely got my business for any future problems and ill be telling anyone i know about them ........garrett tuning for the win !!!!

We used the Ford PATS delete service. Worked great. Very quick to respond and fix and ship back. Will use again. Very knowledgeable.

Purchased a preprogrammed fuel pump control module. Installed and truck runs perfectly. I’m a business owner and like this smaller type of owner/operator shop because you’re dealing directly with someone very knowledgeable in their craft that wants things with their name on it done correctly

Very knowledgeable and professional!Provided me with a new PCM, specifically programmed it to my vehicle using the VIN, and then tuned it to my requested specifications! PLUG AND PLAY EXCELLENCE!Garrett Tuning… a highly valued resource in my Garage!

I rarely leave reviews, but I gotta give a big THANK YOU to Garrett Tuning. I was in desperate need of a ECU for my vette. I had my new/used programmed ECU in 3 days. There was no need to go to the dealership. It was literally a plug and play. Thanks again guys..

I bought a replacement ECM for a 2003 Buick LaSabre that was exhibiting a constant high idle. The replacement had obviously led a hard life, but it works great! Thanks for the quick shipping.

Went for AFM/DOD delete on my truck. I modified the valley cover and replaced the failed lifters, Brad had my tune/delete done extremely quick. Im not wealthy so his price fit my budget perfectly. Now I dont have to walk to work anymore! Thanks Brad!!👍

I ordered and received a used, reflashed ecm for my truck. (No mention of them being used) New ecm lit up like a Christmas tree on the dash and had more codes thrown than the previous stock ecm. Garretts Tuning was responsive by email until I mentioned having issues, then I got zero responses. After installing the stock ecm and starting at ground zero I reached out to try to return the ecm. I was told thats not a possibility. Garretts Tuning should have a no return policy listed on their site if this is the case.Also seems silly to me that a USED ecm cant be returned and then flashed to a different vehicle. A restocking fee would be justified in my opinion.

We shipped our trucks brain to Garret on Wednesday, for reprograming. Garret received it Friday, reprogrammed, and shipped it back out same day. We received it Monday and were back on the road! FANTASTIC!! Could not have asked for better service or turn around!

Super fast turn around on an ECU adjustment. Would definitely go to these guys again

I Ordered a New Computer for my Chevy Silverado, I wasnt 100% certain what to do online, so I called them. They were very helpful on the phone. They Immediately sent me what I needed. When it came I installed it, But I was worried at first because of all the You Tube videos showing how to program it, But I didnt have to do anything, It started right up and Ive noticed over the past weeks that the engine is running better then before, . Thank You

Great guy with for tuning your car

Just received my cars computer back from Garrett Running after getting the SKIM delete service. My car wouldnt start due to an issue with the SKIMsecurity system and is now up and running again. It was a simple process, remove ecu, send in with order number and when you get the computer back make sure to remove the halo under the ignition cylinder. Highly satisfied with the work.

I needed a PCM/ECM for my Chevy Suburban, I called Garrett Tuning and spoke with Brad. I gave him the info he needed to program my part and he got it done and shipped to me very quickly. The part arrived and I needed some pinout diagrams and Brad got them to me. They helped me trace down a wiring issue, I repaired it. I installed the programed PCM/ECM, did the re-learn procedure - turned the key and my Suburban started right up. I recommend Garrett Tuning and rate that business at a 5 star rating for helping me get my Suburban back on the road!!!

Ordered a computer for 1996 Chevy 3500. It installed and worked perfectly. Thank you very much for the prompt service.

Good car guys, finally!

There I was in second gear. A seemingly typical Monday morning on my way to work. Without causes known to me my light indicating a malfunction occurred lit up.After a few moments of research with the known trouble code I was pressed for a new module for my Corvette. The team, namely Brad, was excellent and quick to work on confirming my diagnosis and supplying me with a new and improved module. Thank you so much!

Great business, u ordered a part from them, it took a little to get it due to some programing issues but once I got it, put the part in a d it worked great. Thank you

I got the TCM that I needed in one day. Unheard of! Having such an option was vital for me. Garrett was very friendly, knowledgeable and went out of his way to make sure I get the TCM in a timely manner. Thanks Garrett for help. The part fit perfectly and the upgraded programming solved a problem with my transmission that I had.

This place is amazing Iam Ronnie from Jacksonville Florida I own a few auto shops and needed a computer for a Saturn, and I contacted Garett tuning and not only were they the cheapest out there but I received my package in three days which is unheard of. Computer worked great and came with instructions on how to install, it was a great experience and we will be doing business again thanks

2011 2500HD 6.6 TCM went out called them up and he programmed a new one while I drove up to pick it up. Plug and play took 10 minutes.

Great for quick and friendly service.

Dont buy parts from them, they say they are all new parts but no warranty on them.

It works.
