So, have you noticed a difference in perfomance bewteen your car fully loaded with passengers and just you driving, because that's exactly the same difference you can expect with the tune
cool...thanks for that!....

I've noticed a significant difference when driving with another 3 people in the car.....now I know they're "worth" 50bhp LOL....

Unfortunately, 400hp+ is not realistic from remap alone, we would expect to get the car to just under 400hp (380-395hp)



The price for this upgrade, including before and after power run is £895.00+VAT



However, Kleemann have strongly advised, to get the best gains out of the car with the re-map, they would suggest to upgrade the Headers, and swap to a 200cel Sports Catalyst, which will allow the engine to breathe a lot more efficiently, with a massive release of restriction from the original catalytic converters which strangle the big 55 motor.



Gains then up to 420hp will be achieved ( +60/80hp), with a massive improvement felt at the top of the RPM where the car will rev out a lot crisper with more punch.



The Kleemann headers + 200cel sports catís are £1495.00+VAT



We offer an option for Heat Treatment on Headers, which provides noticeable improvements, especially for N/A Motors (some photos attached of a E63 Log Type Header from Kleemann that we have recently installed), this stops a lot of heat conduction to the motor, and more importantly, keeps the heat inside the headers to promote hotter gas and hence quicker gas velocity through the header (hotter gas travels quicker to colder area). We coat the headers and then wrap, and re-seal the wrap with high-temp paint sealant, all making a very neat heat protective coating to the headers, the price on this service is £550.00+VAT including parts and labour



Fitting on the headers and the sports cats will be 6 hours x £65.00+VAT = £390.00



IN SUMARRY



K1 ECU UPGRADE = £895.00+VAT

K2 ECU and HEADERS UPGRADE (WITH HEAT TREATMENT) = £3330.00+VAT



Some Attached photos of the Kleemann Headers for 55 V8 Motor (not wrapped)



We also offer Lowering Modules, Rear LSD Units and Brake Upgrades for your car that will transform the handling completely
and id say with new headers, 100 cell cats etc etc i think maybe 50 is possible but its 4000quid. my opinion (which dont mean shit) is to keep it as standard as they are mint mint motors. and boy do they sound orgasmic.

I agree mate going to leave it as it is and just do a few subtle mods.

Fitted LED number plate bulbs which look good and having the interior a pillars, roof and rear window trimmed in alcantara. Maybe have the interior trimmed in leather as Palmnuts did.

I dread to think but I know they make the engine 6.1 litres and 440 BHP. I am guessing 10K at least.
