For those of you who were at the RR day yesterday you would have seen my car embarrass itself and post a very low 253.0 bhp
This time last year it was a whole 4.1 bhp more and since then I have a new RICA 310 map a Forge recirc valve and Volvo TCV amongst other things.
The car now has a fair bit more torque 311.9 ft/lb compared to 274.0 ft/lb and drives well on the road, but.....as you can see from the graphs below this years has a dip around 3300 rpm which for those who weren't there yesterday was accompanied by 'chattering' sound.
Do any of you have any idea where I should be looking, maybe a new Forge actuator is on the cards as it's never been changed and I've been told the diaphragm can go in these, along with maybe an IPD TCV, anyone use these items ?
Hopefully someone can point me in the right direction, help as always greatly appreciated.
