I sent in the ECM for my 2006–2007 Lexus IS250 2.5L on June 4th and received it back on June 13th. USPS managed to lose two days in transit both ways, but that delay had absolutely nothing to do with Richard.
Before the repair, my car had a harsh downshift from 2nd to 1st and an occasional hesitation when dropping to 4rth from 5th. After Richard’s work, both issues are completely gone. The car shifts smoothly again.
Richard’s customer service is exceptional. He messaged me the moment I placed my order, updated me when he received the ECM, and notified me immediately when the repair was finished. His turnaround time was unbelievably fast, easily the quickest I’ve ever seen for automotive electronics.
The communication was flawless, the repair was perfect, and the price for this level of service is very reasonable. I honestly wish he offered even more Lexus repair services. Don’t hesitate to trust him with your vehicle’s computer.
