Simon,
If your car has the earlier Motronic 4.4 ECU, you will certainly not be disappointed with the purchase of a TME engineered software upgrade priced at £299 plus VAT.
TME and I have particularly priced these earlier upgrades in the UK at a very fair market price as the high cost of some similar competative offerings can represent a substantial percentage of the current market value of these cars. With their very high turnover of this product over many years, TME have amortised much of their original developement cost.
If you are considering other physical items such as exhaust components then I can offer some very sharp prices.... but you will need to contact me directly.
