I am getting some pinking around the 4k rpm range when the engine is under load and its hot outside. I have tried various fixes via my TVR independant but it still seems to pink a bit.

The car is a 98 450 with 44k on the clock. It has been serviced, had a new stock cam and had the pre cats removed, new ht leads, new coil and a mildly modified chip from TVR power.

Where else do I look?
