Chris Alger's Historic Stockcar in for setup I have sponsored Chris for a numbers of years now and it only comes in when really needed or there has been changes as Chris is good at maintaining the carb and the car. Definitely a lot better then when it come in as adjustments needed for the changes

Well done Joshua Machin on being 2025/2026 National points champion

A 1300 now called 1400 Stockcar I sponsor the tuning side and the engine taken care of by CSR engineering Chris Skinny

Well I had to get one right at some point i suppose 😂 not to bad for someone who not got a clue about tuning 👀 it does help when the tuning goes alongside a well setup car that doesent handle like a shopping trolly and a driver that can actually drive!!... its always easy to blame someone else 😂

Also the others who put time in for Josh
Melv Henry
Bob Young
Charlie Henry

Sorry if ive missed anyone

Team #20 #36 💪

Paul Frosts FWD Hotrod in for a setup prior to its debut meeting at Yarmouth Stadium tomorrow running a Kev Randell built ST170 engine. This should be a fun car out there plenty of power and torque in something that weights a little more then a cigarette packet power to weight ratio is 👌

Im not normally one to shame another companies work but its becoming a common occurrence and a bit boring putting there work right and to be honest the files that are being flashed onto people's vehicles are a complete joke!!

When you have yet another vehicle come in and asked us to check over a map that was done because they wasnt happy and didnt really get any help or changes after several visits back to them so I pull the file of the ECU and find this half hearted attempt its madness!!! Its compared against a 100% Standard file

I have dropped the file into ECM to make it easier for people instead of winols to see

The file on the left is there file and the file on right is ours the changes to each section is shown via the ■ beside each section if doesent show a ■ beside it the software is showing its 100% standard as manufactured and not changed!!

Now when you tune this type of Vehicle you have to tune ALL the limiters that needs doing as well as the fuel rail pressure and as you have guessed it THE BOOST how you can tune this and not add boost ill never know its absolutely shocking 😂😂

Now when you see a remap offered for £150 you are going to get that value !!! and pay more then that to have it corrected...

Some questions to ask them is... are they "Master" tuners if so they can see the file and alter accordingly or are they a "Slave" tuner who will see absolutely nothing and cant alter anything all they do is send a file to a "Master" who alters it and send it back and they write it on. Also one of the most important questions is what mechanical background do they have are they qualified or times served do they even understand how an engine works and how to interpret live data and logs etc... if they cant answer them questions then why let them work on your vehicle!!!

There is some really good "Slave" tuners out there who are connected to good quality "Master" file providers so im not bashing "Slave" users at all im simply saying there work is only as good as there Master.....

Cheaper is not always better and its 1000% proven here this customer now has a vehicle that actually performs and dont smoke like a train !!!

Not something we actively do anymore but having always done Michael's stockrods it was in for a few tweaks and a catch up.
