Advance the ignition timing a little at a time.

Is this where an air fuel ratio set up could help?

Check your exhaust is not blocked (especially if it has split in downpipe).

Had the same thing with faulty fuel pressure regulator. Although with that also came hot start problems.

Fpr is fine the diaphragm seems fine never had hot start problems probably worth putting a gauge on to see the pressure though and the exhaust is brand new thanks for the suggestions though

Ignition module? Have you got heat paste on the mating face?

It's a new Bosch item and has the proper paste ????

the exhaust is brand new thanks for the suggestions though

Has this issue only appeared after the new exhaust has been fitted????

Unfortunately not it's been there since I owned the car

Correct AFM for the car? Sounds like it's going lean. Do a hard cut, coast to a stop and check plug colours.

Yh that's what I think out of fuel up top wondering weather the signal for the throttle switch is not working the throttle switch itself works fine , hopefully get it on a RR and see what that tells was thinking of blocking the fuel return or blocking the FPR just to give it as much fuel as possible just to see what that dose to the revs up top thanks for all the help and suggestions
