As a few people know I am practically always developing new stuff in my spare time, so my free retunes policy take up a lot of my time then for the last 18 months I have been busy with a huge contract or 2... that a few people know of and have seen me deeply involved in.
Right now, I have basically cracked about 40 new tables in the ECU wide open and suddenly 200Kw from VF52 WRX's or Liberty's with just a dump pipe are now easy on less boost than ever before... a LOT less. 15.4psi VF46 tunes are now getting 120Kw@wheels at 2700rpm, 16.2psi VF56 tunes going 135Kw@3000rpm and GTX2863R going 154Kw@2700rpm on 18psi on pump fuel. By running less boost, the turbo exhaust wheel becomes less restriction to flow and the size of the turbine outlet and wastegate flap no longer hinder airflow through the engine, resulting in an engine much more willing to rev and more importantly make a higher peak power. I have the compressor flow charts from FHI for the VF series turbos so boost pressures are optimal and result in longer turbo life as well
Here is the cool part... I can now lock the ECU into Write Only under some conditions which I will get to... So if you want to get a retune from another workshop at some point, they can copy a stock tune over the top and it removes my lock and my unique identifier. You or your workshop will not be able to download my tune but each customers tune will have a unique identifier in the tune, so pending paperwork, if I load on a tune and you wish to purchase a full extended 3 year engine warranty on the tune for an additional fee, it will be possible. The tune must be loaded in person by me, the identifier must be present during an ECU scan if an engine failure occurs to ensure you did not have it tuned elsewhere and the software will also tell me if major mechanical changes were made(insurance underwriter has this as a condition) and the engine if requiring replacement will be a complete factory replacement. No upgrades or forged motors unless you pay additional parts/labour
Obvious timing belt or waterpump or oil pump failures, 'some' headgasket issues and known big end bearing swarfe issues in some early 2.5's will be excluded as would water flood damage or low engine oil issues, the ECU and BIU will KNOW

All work will be carried out by a Nationwide workshop network where the car will be towed for assessment and engine replacement. Expected engine replacement turn around is 3 business days. Cars fitted with a CAI of any type, unfortunately, will be unable to take up this offer due to not being ADR approved(insurance legality) but a full Turbo back exhaust with atleast one catalytic converter will be covered. Some existing customers who meet the criteria will be able to take out the offer as well

This importantly will also cover my E85 flex fuel tunes
Final details and pricing for this warranty are in progress and expect to have more information shortly. Pricing is expected to be extremely attractive for this offer as well
