Here's a pic of the temp during first run test (stock)
I have the fuel graph too if you want.
There were three runs in total,only saved 1st and 3rd (called run 2 on graph)
Fans that blew at front of car were same speed for first two runs.
Actual 2nd run showed car was running a lot colder an fuel was leaner.
Actual 3rd run, lowered the fan speed slightly,and the temp & fuel were similar to first run but power gain was highest
(2nd run showed 181.3 bhp)
Apart from the filter the car was not touched.
If you want I will video the run for the exhaust(though how to host it is another thing)
