Took my 306 here today that required more power 😇🙈 all I can say is what a fantastic job he has done. the car has so much more power 😍. He also diagnosed issues that I wouldn't have found. thank you for your 5* service. highly recommended.
I had my peugeot 207 90 HDI mapped for VNT turbo by Steve. The car runs faultless and moves pretty quick. The online service it s very fast, comprehensive and at the right price!
Great fast service, very knowledgeable, my ds3 1.6 diesel runs so much smoother and faster after it’s remap. Highly recommend this company.
Remap done by Steve. On hand advice and a wealth of knowledge. Put simple the guy knows his S#*T. After remap had an unrelated fault and Steve was able to diagnose over the phone and it cost me a fiver to fix myself (actually about 50p of vac pipe) but I got plenty left. Cheers HDI Tuning.
Steven is a top chap. Sent the files for my Suzuki Vitara via email and totally transformed the jeep. More torque across the whole rev range and gained about 10 mph on top speed. Total value for money. My brother in law is now ordering the same service the day I done mine! 5 star service and 5 star MAP. Thanks again Steven :-)
