Have had multiple vehicles here and will continue to bring these guys more business in the future. Extremely intelligent staff with meticulous work, from tuning, to engine rebuilds, to custom fabrication. If anyone is thinking about having a GM vehicle tuned, this is the place. In house dyno, thorough explanation of what the strategy is ongoing any work performed, as well as competitive pricing! I needed some Holley parts and was talking to them....come to find out they are a Holley dealer! Parts, labor, knowledge, cleanliness, organization....all top notch!Services: Transmission, Auto engine tuning, Engine repair

I have nothing but good things to say about Maysn and Tim. I ve had my Firebird in their shop for various upgrades and came away happy and very satisfied every time. Maysn has worked on my Firebird for most of the 20 years I ve owned it. FSI really knows their way around LsX motors of all sizes and levels of HP. I recently had them retune my Firebird on their Dyno and left with what I felt was the best tune I ve ever had. (The previous tune was at a shop Maysn worked at but not by him). I wouldn t trust my Firebird with anyone but Maysn and Tim. I d give them 6 stars if I could.

I have a 2019 Chevy Camaro 2ss convertible. I came in with some tuning for the throttle body issues i was having and a trans tune. My camaro started out with a 112mm granatelli tb which was tunable with my issues is what i was told. I knew the throttle body was larger than normal but with the issues i had using a particular brand i decided to try an over engineer and install the 112mm tb. After a week or so i was told my car was ready but there was some issues with HP tuners and would have to return for that. In addition the car dyno tested lower than originally tuned but numbers aren't everything its how it runs so i decided that was expectable if it runs good. The cam idle was very different and didn't have that rhythmic lope i am used to hearing and feeling which has been a part of every cammed car I have ever owned but decided to take it anyway and see how it acts. The next day cold start the engine was backfiring cracking and popping very unusual behavior in addition the cam lope is abnormal and kinda sounds like its misfiring to me. After a couple days of this i decided this needed to be looked at again. Dropped it off again for repairs and the trans tune we couldnt do before. Keep in mind this is not close to my house about 1 hour 20 minutes one way which i was ok with to finally have someone tune this like it should be so i thought. After 3 more weeks i was told the 112 mm throttle body could not be tuned and i needed the 103mm tb. This was the original size i had before installing the 112 so in my mind i wished i would have been told that before i was delivered a finished product and paid aprox 1100.00. If all i needed was a 103 Tb then i didnt need tuning as i was reasonably happy with the original tune. Being i was already into this for 1100 i purchased a used 103 tb from them so they could continue. I was told it was ready for pickup and runs great no issues at all. Paid for the throttle body, started up and the cam didnt sound like i remember it nor anything like i have ever herd but decided to drive it and see how it does. Immediately i noticed the throttle was way to much to fast, i couldnt even go around a corner without racing around it, i thought this might work in but after feeling the transmission shifting way to hard under light throttle, turned around and brought it back very unhappy. I asked them if they could load my old tune back in and was told no. My confidence is very low with them at this point and i wanted to stop here and just get a refund to try something else but was told no. In addition my car was nearly empty on fuel after they test drove it to try and convince me it was good when we all knew it wasnt to be completly honest. Went to take a test drive to log a drive file and couldnt cause it was out of gas and no gas station within reasonable distance with E85. I left very upset and said i would be back in 2 weeks let me know if you cant fix it. Was told it was finished again so i made another trip nervous but excited also. I didnt even to 4th gear, gears 2nd and 3rd shift so hard i nearly though i was going to drive off leaving the diff behind me. Drove back for some more adjustments and was told it was good. There were some parts of the tune just to be fair i thought were outstanding but the other issues i just cant live with. Now keep in mind i had already had a tune with a 103 tb and didnt have any of the issues i am having at this point. I drove home with the throttle still way to much to soon i mean the response in my opinion was triple what i would even consider safe to drive on a public roadway. The trans shifting was still was to hard 1st to 2nd and the adjustment didnt do much for 2nd to 3rd, in addition the check engine light and the stabilitrac warning lights came on before i even arrived at home, they wanted to disable random misfire, no, you shouldnt. now i am stuck with a car i cant drive they cant fix and wont refund my moneyServices: Transmission, Auto engine tuning

Tim Jayne (Nub) is awesome to work with. Anytime I reach out with questions he always answers and gives time. That's rare. His knowledge is superb with LS platforms and I can trust their work. Hands down a great shop with integrity.
