Referred to Speartech by Ken Wolkens to get my ECM tuned correctly. Reached out and contacted Justin.Justin worked tirelessly to make sure my issues were resolved and always offered advice and instruction and was spot on!He always answered my emails and followed up. Through his knowledge we were able to get this LT swap figured out.If I would have know about Speartech from the beginning I would have had them do the harness as well (not that it wasn't done correctly by Ken).Thanks so much Justin!Phil A.

I order online parts from different sites and its my first time ordering on Speartech.The tech support (Justin) emailed me after I ordered and I personally did a mistake on my side and order an extra item by mistake so he returned the item before shipping and asked me about the items and for which engine model that I will install it for to make sure I recieve the correct items with the correct harness.I will definetly order again from them if I needed an item that they offer.10/10 serviceImage: Proof of order so you know its a real review..- Ahmed

Well worth the wait. Their system is as close to plug-and-play and you can get. Top notch customer service too. Had an issue, not sure who’s fault, but either way they helped troubleshoot the issue, and resolved it in the same day. Justin, thanks for all your help!!

I have a 1949 Chev truck with a LS . I first bought a harness from Speartech after a local harness guy let me down. It was a trouble free and helpful sale from the start to finish. I was having a DBW issue from day one on this conversion . I had the truck to local tuners and NO ONE could get it right.( just a lot of "I think" or try this ). Much money was spent and still not fixed!! I talked and emailed Justin quite a bit ,we went through the whole truck again and Justin was 100 %sure that it was the way the tune was done.. I installed a new tcm and ecm and the truck now functions like new. I CANNOT SAY ENOUGH about the customer service. Never make you feel stupid and takes the time to get all the info.. Thanks Again.. Wes

I called these guys and left a message all the way from San Antonio TX... I thought they could maybe help me with a harness for my LS9. With in an hour justin called me back and spent 20 mins walking me through. He referred me to a dyno shop in TX that were legit and even gave me there #. Its rare to day to have a business take a moment to help someone out with no monetary reward! Justin was super knowledgeable and a true professional!! Thanks Bro!!

The best type of company to deal with. Fast communication and there was a misunderstanding on my part and Justin resolved everything. These are definitely the guys you get in contact with if you are having any type of ECM/ TCM issue with your LS swap project (in addition to the other services they offer). Hope to come back to these guys for all my programming and harness needs in the future.
