Quick update as it's been such a long time since I got my 380 back after it's work. I've put a thousand or so miles since the TVS1900 got its EX500 chargecooler upgrade and the Delta ecu and 2 things are obvious: the operating temps of the engine are so much lower, before the work it always ran hot and you could literally feel the timing being pulled along with the reduction in power. Its chilled all the time now, even sitting in standstill traffic on a hot August day.
Secondly the torque....the bump in mid range is HUGE, so much so that I've had to recalibrate my steering inputs. Mid-bend it will really punish you if you aren't on your game. It's a very wide eyed, triple shot espresso after affect from a spirited drive on my favourite roads.
I'm chuffed it can deliver the performance on repeat, even on hot days and at a super mild 6.5psi boost.
As for the Delta ecu....I couldn't tell any difference from the Lotus oem item as it was fitted and mapped at the same time as the EX500 kit (Komotec chargecooler, front heat exchanger, fuel rail, etc). All the factory stuff works including the cruise control, etc. I'm not sure what I was thinking though as the Delta guys are ex-Lotus engineers.
Other than the final engine mods it's had some detailing and porsche white gold highlights.
Love this car sooo much, in my mind there really is nothing to touch it.
