Went in for a part for my truck. The guys took great care of me & my truck! Great experience & definitely recommend.

Ordered a Stryker Module for my truck. After multiple attempts to contact the company(phones would go to voice-mail and voice mail was full) I sent an email to cancel the order.Two days go by with no reply to my request. I made another call and finally speak with someone who was rude, couldnt answer simple questions, and refused to put someone on the phone who would be able to answer (its not their job to talk to customers). Would not send an email in reply to my cancellation request to say they were working on it. Apparently Im supposed to be happy with no communication after spending more than $700.I was then hung up on.This is not the customer service the representatives preach they have on the truck forums or anywhere else Ive seen.I am so glad I did not find this out after I had received the module and could get no support from TS Performance.

I purchased an MP-8 performance chip for a 3126B Caterpillar diesel from TS Performance a few years back. I began to have hard starting problems with it immediately, and was never convinced that it worked at all. After removing the chip and having the engine run normally and perfectly, I contacted TS Performance to get an opinion and warranty service. I returned the chip for service and reinstalled it upon receipt. I encountered the same problem as before. TS Performance refused to pay for shipping to check it out a second time, so I was again out over $30.00 shipping again in addition to the $500.00 that I originally paid for this worthless, or even problematic chip. I repeated the process of installation once again after getting it back the second time with the same results, no starting! TS Performance has refused to refund my purchase price.Do not purchase anything from TS Performance. There are better and more reliable performance products on the market. TS performance has terrible customer support, no communication (they never answered my emails, nor returned calls), and makes promises that are not kept (They promised to check my chip on an actual engine to confirm the repair. They did not and never informed me either way!) Shop elsewhere!

These guys Rock and Wake Up Powerstrokes

Terrible experience..a nice website but pure scammers - have you seen the movie deliverance? I think that was filmed in Kentucky

Hi just installed a new MP-8 pro. in 2003 international vt365.nooooooo anything!!! this is useless!!! called customer support. now I have to pay shipping to send it back to be checked. Wow am I not a happy customer. Also remember before purchasing. with a return you will have paid for shipping 3 times. for something that is not your fault!!!!!!

I bought a product that didn’t work and sent it back to be sure there was not a programming issue (within 15 days) with the programmer and now they want to charge me for shipping and device fees. What a joke! I won’t buy another item from this place and would not recommend them to anyone. Customer service sucks!

These guys ARE diesel performance! Dennis and Sheila are the coolest!

Didn’t even have basic products. Zero help to find any couldn’t even get a fass fuel
