Czipar Performance 8610 U.S. 52, Dubuque, IA 52003

"I've been going to Tyler and his team at Czipar since 2017. They've tuned two of my 2015 Caprices, done motor work and tuning on my 2001 rcsb Silverado with a 6.0-80e swap, and most recently did a full DOD delete and cam package on my 11 Escalade. Their work is timely, top notch, and inline for the quality provided so far as price is concerned. I travel over 3 hours both ways to use Tyler as I can't trust anyone in my area, and that concern is based on real world experience. If you're looking for an honest business owner who stands behind his offerings, trust Czipar Performance of Iowa."

"Tyler came through with an excellent tune on my truck and completely turned it around from the previous tune that was done on my truck by another shop after having a cam installed. My truck initially would hesitate and surge when taking off, once it was warm it wouldn’t stay running on its own at start up, you’d have to give it some throttle to keep it running, it would even stall randomly while sitting at like a stop light. It also was struggling to pull my trailer that was only half of the trucks towing capacity. I threw so many parts at my truck thinking I had done something wrong or there was a faulty part somewhere that I couldn’t find. Luckily I found Czipar and after a quick phone call I had an appointment set. Confident they were going to get me dialed in, I made a 4 hour drive out to Czipar. The drive was more than worth it, it’s such a night and day difference with the performance and driving ability of my truck after he tuned it! My truck now starts and drives so good and pulls great, I couldn’t be happier! I’d highly recommend Czipar to anyone looking for a tune or performance work, especially if you have a 14+ Silverado / Sierra!"

"Tyler was awesome to work with and did a great job tuning! It made a big difference after doing some additional modifications and glad we made the trip over to see him! Greatly appreciate all his help and being a reliable performance shop for great work! Thank you!!"
