Went to a Corsa Sport rolling road day Sunday as my mechanic was involved in organising it.
The place was Perfect Touch in Hoddesdon, there rollers are by far the best I have ever seen, the grip on the rollers is mad and the fan without going OT could probably blow u over if you stood next to it. To give you some idea the cars where going in dripping wet from rain and coming out bone dry!
Anyway my car made 260bhp and 311ftlbs as u can see below. Now the problem was pointed out by the operator straight away and said i should be able to feel this on the road which i can.
It is after 5 - 5.5k rpm power/torque is all over the place and just drops in a big way, now i have posted before about my boost not being right after 5k rpm.
The guy there basically said this is down to a bad map on the car and after 5k rpm the car is leaning out and the ECU is trying to compensate this by throwing a load of fuel in and backing boost off. He said if this was not happening the car should be making anywhere between 280-300bhp.
Anyway after speaking to my mechanic he said i should have a word with the guys as they do Live Mapping.
After a bit of a chat with the owner he said he could live map the car no problem and was so confident the car would be much better that if i was not happy when i got the car back i would not have to pay a penny. He said i am not promising more power but the car without a doubt will be faster on the road because of the way and where the power is produced.
I am tempted to go down this route as Perfect Touch is not all that far from me and the guys there could not have been more helpful. The owner also mentioned he did not advertise anywhere all his work is done through recommendations and that i should look on the skyline and fiat coupe forums. I had a little look and it seems people cannot praise them enough.
Live mapping is £450+VAT and they said the would could need the car up to 2 days as they will not give the car back until as far as they are concerned it is perfect but normally done in a day.
I am not 100% what to do, what do guys think?
