“Map itself is fine but communication wasnt great. Told me 2-3 hours, ended up taking all day and I had to chase updates. Car drives ok though.”

“Absolutely brilliant from start to finish. Explained everything clearly before starting, showed me what they planned and checked I was happy first. Car feels much livelier now, pulls through gears proper, and iv actually seeing better fuel economy — around 4mpg up on runs. Very happy, would reccomend.”

“Check engine light came on, took it to a local garage first who just guessed and wanted to replace parts ££. Avon found the exact fault in under an hour, showed me the readout, told me what was needed and gave a straight price. No nonsense, straight talking, honest.”

“Wow what a difference. Torque is night and day, dont need to thrash it anymore, just pulls strong through the rev range. Kept me updated through the day, told me when it was half way, when testing. Top blokes, fair price for the work done.”

“Improved MPG like they said, though not quite the full figure quoted — got about 3.5mpg rather than 5 they mentioned. Still worth doing though, much smoother to drive. Polite and explained everything even if it wasnt the biggest gain.”

“Came to my work place near Bath which was dead handy. Diagnosed an electrical fault that had been bugging me for months, traced it quick and fixed it on the spot. Travelled out to me, turned up on time, tidy worker. Would use again.”

“Electrical gremlins had me stumped, dash lights going crazy. Avon traced it in couple hours, found a corroded wire nobody else spotted. Honest price, didnt try and sell me a new loom or anything. Good lads.”

“Car feels like it should have done from factory. So much smoother, no flat spot at 2k revs like it had, pulls clean all the way up. Explained what they could and couldnt do, didnt promise the world. Great job.”

“Activated some hidden features on my BMW — carplay works now and updated the maps. Took a bit longer than they said it would, about 30 mins over, but got there in end. Works perfect now.”

“Went the full Stage 3. Explained clearly what parts were needed, what the limits were on my engine, what power to expect. Ran full health check first, custom map built for my spec. Runs beautifull, very thorough.”

“Persistent warning light nobody could shift. Other garages just cleared it and sent me away. Avon dug deeper, found the actual sensor issue, replaced it same day. Explained it simply without the tech babble.”

“Good improvement overall, noticebly better low down. Had to chase once for an update though, wasnt told it was running late. Once it was done its great, just communication could of been better.”

“Got the eco map done on my work van. Running costs down nicely, can really tell on longer runs. Came out to me, mobile service worked a treat. Knows his stuff, recomended to the other lads at work.”

“Timing belt and water pump. Gave me a clear quote upfront, parts fitted were the right ones, done when they said. Kept the old belt to show me the wear which was a nice touch. Trustworthy, hard to find these days.”

“Did a full health check first — found a minor issue I didnt know about, told me before touching anything. Got that sorted then mapped. Car drives beautifull now, pulls hard but still reliable feel. Top work.”

“Came out to me in Bristol which was great. Fixed the issue quick, though travel charge was a bit more than I expected when booking. Agreed it upfront so cant complain, just something to ask about first.”

“Arrived over an hour late, then said he couldnt do the job after looking at it. Charged me call out fee anyway. Disapointed by the whole experience.”

“Car is transformed. Dont need to drop gears on hills anymore, just pulls. Explained every step, showed me the graphs before and after. Very professional, fair price.”

“Saved me a fortune. Told me exactly what was wrong AND what DIDNT need replacing. Other place wanted to change the whole system. Will be back for anything else.”

“Good result overall, car much better to drive. Did take longer than the slot booked though, nearly an hour over. Still got it done, price stayed same, just plan for a bit extra time.”

“Door module playing up for weeks. Sorted it in an hour, kept the old part to show me exactly what failed. Didnt mark the trim, very carefull. Nice bloke too.”

“Wanted better driveability AND better mpg. Got both. Car smoother, easier to live with, and im getting an extra 4-5mpg on motorway runs. Exactly what I asked for.”

“Found the fault ok but parts took longer than expected — about 4 days wait. Kept me updated though, called when they arrived. Communication good, just supplier delays out their controll.”

“Enabled carplay and coded the new module. Done at my house via mobile service which was brilliant. Showed me how to use it all, didnt rush off. Tidy worker too.”

“Excellent advice, told me exactly what my car could take and what was pushing it too far. No overpromising like some places. Result speaks for itself — pulls fantastic. Very knowledgable.”

“Economy improved about 3mpg. Helpful but not massive gains like you might hope. Still honest about it upfront so no suprises. Professional and polite throughout.”

“Brake service and electrical gremlin. Checked everything before starting, told me what was needed and what could wait. Done proper, not rushed. Good honest work in Bath.”

“Second time ive used them. Transformed my last car and this one too. Straightforward, no sales rubbish, just good work. Price fair for what you get.”

“Result is ok but took 3 attempts to get the map right. Kept having to go back. In the end its fine but the process was frustrating and took weeks.”

“Found the issue eventually but took longer than quoted — ran into something unexpected. Still got sorted and price wasnt hiked up. Competent just allow extra time.”

“Massive difference low down. Dont need constant gear changes on country roads anymore, just pulls. Explained what they adjusted, kept it simple. Very happy with the money spent.”

“Fixed the wiring issue that was draining the battery. Good job done, though a bit pricier than I thought it would be. Quality work so worth it in end I suppose.”

“Talked me through every option, told me what suited my driving. Custom map not an off the shelf one. Car pulls like a train now, smooth right through range. Great service.”

“Warning light came on, got it checked. Cleared the code and explained what caused it, told me to keep an eye. No pressure to spend money just to clear a light. Nice to deal with.”

“Showed me before and after figures which was good. Drives smoother, stronger, no issues. Called me when they started and when finished. Professional all round.”

“Got about 3mpg better. Not the 5 they said might be possible, but still an improvment. Friendly and honest, said results vary by car. Cant fault that.”

“Came to me out in Somerset. Fixed the intermittent starting fault three garages missed. Knew exactly what to look for once he saw it. Worth every penny.”
