if you need any help over here let me know, ive had a few future m35 buyers come over to to check my car out so the offers there etc.
you have two choices at the moment for tune/dyno:
C-Red in beckenham they will do dyno runs for you no worries, for tunes c-red also do tunes only e-manage at the moment.
Or theres my tuner he does HKS f-con which is what I'm running on.
You could try hyperdrive or PZP but id stick with guys who have had experience on our orphan cars.
you also just missed the first M35 stagea meet i organised in kings park last sunday!!
