Electronic Diagnosis

“I have a 2014 Jeep Grand Cherokee v6 diesel 8 speed auto with 140000km and would like details re an engine remapping and before and after details and costing if possible. Currently returns 8L/100km urban/suburban driving and under 12L/100km towing Jayco Silverline at 90/95KMH. Thanks Alan”

“I was at my wits end when I took my car to Exceltune. I’d owned it for a few years & was never happy before me had done to it. It had an aftermarket exhaust, K&N filter & possibly a previous tune, but it drove like a turd. I consulted 3 euro specialists (2 in depth), & couldn’t believe they weren’t straight onto it. Jacques spent the time with me (we went for a test drive, he drove, I explained), he got it. When he said he would fix it or I wouldn’t pay, I was hopeful but sceptical. I still own, he still services it. I drive across town, it’s inconvenient, but I was so happy with the job, I go back. It was a while ago so you’d have to ask him about pricing. If I hadn’t found someone who could fix it, I’d have sold it (or crushed it) long ago. Matt”

“Very impressed and amazed at my service history !I have been taking my Volkswagen to Exeltune since 2014 for general servicing and repairs . Jacques go above and beyond , great professionalism and customer service , imported cars expert. Thank you Jaques”

“Took my Mini F56 JCW to Exeltune for an ECU Remapping, it was done within 3 hrs, then took it for a test drive. Wow I can feel the immediate gain of power and torque the second my foot was on the accelerator, engine responsiveness and throttle was awesome. Overall I was very impressed with result and it was a pleasure to deal with Jacques, I find that he’s direct and honest, extremely knowledgeable. Would definitely go back to Exceltune if my vehicle needs work done in the future. Highly recommend Jacques to anyone decide to get ECU Remapping.”

“These guys know their Euro cars and how to tune a diesel engine. I have a 320d msport and this as standard is not such a quick car but with the service and tuning from exceltune the 0-100kmh time dropped by over three seconds with fuel ecomomy still quite good.”
