Just Engine Management

I got to say, i am extremely amazed with the work these guys have done to my S15 - 321KW SBEI came in with my S15 in a bit of a mess and meeting Waseem was more than happy to give a lending hand and giving an extreme warm welcome to JEM, Waseem went over my car and we decided on the the goals on what power i was aiming for.After setting my goals which was above 300KW SBE, Waseem started to list out my needs and what works are to be placed. With every part of work Waseem mentioned he always gave it an option with recommendations and what are the pros and cons to each change and part. You actually learn quite a bit.Plans are now set and Waseem and the team have begun the works, seriously the amount of updates and pictures these guys send you will surprise you, with every major change and parts they get they will show and update you on what is going on.As it comes to the tune, Waseem will update you results and will show you what need changes to reach your goals with price tags, like i said earlier, he makes everything an option for you and will recommend what is best.With my results, i am extremely happy with what Adam, Waseem and the team can do, its amazing how they stick to their words and will always give you the best options to suite your needs to reach your goals. This is how it should be done out there, these guys are by far hands down one of the best out there. With a bonus of them cleaning my exterior and engine bay to surprise me.Well done JEM, you have an extremely happy customer. worth every dollar.

Had the worst experience drop my car for regular check-up came back with oil leak and tune had been tampered with, if you enjoy to drive your car stay away from this cow boys, worst thing was I was referred to buy a friend and they knew that!There was no need to reprogram my ECU or create an oil leak absolute scumbagsHope you get what is coming to you guys

These guys are nuts, the quality of work they put into my car is unmatched compared to other car stores, they made sure that everything looked and performed perfectly, corrected previous car shop work and made my car a beast, Thanks boys!

Look I don't know the exact agreement regarding my bro's R 34 engine conversion but I feel disappointed, in the package he got, for the price he paid..Now they are not accepting fault because they claim business restructuring has made them free from Iiability.

Great place great service great people. Need your car modified see these guys trustworthy honest.

If it wasn't for Adam I'd still be stuck, he helped me every step of the way over the phone with my ecu not picking up my dizzy on my 4age 16v. You're a life saver and will be forever greater for your help. 100% recommend these guys.

Perfect communicationCar was brought in running terrible and received it back making the power I wanted an more, great knowledgeable people to deal with, highly recommendCouldn’t be any happier thanks

Massive thanks to Waseem And Adam for looking after and turning my car into a monster. Couldn’t recommend them enough. All legends and tuning experts. Left the shop with double the power it went in with. Thanks again guys

The boys down at JEM provide outstanding service! The level of care and communication is out of this world. I could not recommend them enough for all your tuning needs!
