Alright guys! First post on here, but was very impressed with the info for fitting my RNS-E. Anyway, got a remap last week from Angel Tuning. Quoted 60bhp increase and 90ft/lb. Very impressed with the power, but if you accelerate hard there is a hell of a rumble/vibration which sounds to be from the centre of the car. If you go easier on the gas to get it past that revs then floor it again you can't hear/feel it! (But it does sound like it's doing it about peak torque) On testing the car with the guy he said I needed to drive it more like a petrol and I think he said something about it being the torque?? Not wanting to look too stupid, I just said ok and agreed to change my driving style, so hopefully you guys can help me to figure it out. Have e'mailed him to say I think I'm wrecking my car and what exactly is the noise. Another thought I had from reading other posts was a fuel starvation or injector problem. I'm just hoping it's not a transmission/drivetrain problem!! Any input much appreciated.
