We will map the car to be as safe and powerful as it can be but increasing the power and torque <\/strong><strong>so far beyond the factory specification means it will need appropriately reduced service intervals and maintenance.<\/strong><\/p>\n<p>This package will use the TTS Performance Supercharger kit which we have fitted to many cars, most do over 600PS, our development car was running 620PS 630NM with launch control and flatshift plus multimaps for other fuels.<\/p>\n<p>We would require a deposit of \u00a310,000 to secure parts and booking, and for the car to be left with us for 5-10 working days.<\/p>\n<p>Injectors are becoming a common issue on the B7 models, we do recommend having them removed and replaced for the latest revision, especially if the car is above 80k miles. We do also offer testing and cleaning. Please note that we have come across injectors being seized in place, this could lead to further time being spent on removal as well as the injector(s) having to be replaced <span style=\"color: #000080;\">&#8211; <strong><a style=\"color: #000080;\" href=\"https:\/\/mrctuning.com\/site\/servicing\/#injectors\">for more information about injector cleaning click here<\/a>.<\/strong><\/span><\/p>\n<p>When checking and cleaning Injectors they should always be flow matched to be within 1% of each other, depending on your results will depend on if we can re-use or if we have to replace them.

Fueling:<\/strong><br \/>\nDepending on the modifications to the car, the fuel\/timing is optimised to get the most from these using the fuel in the car.<\/p>\n<p><strong>Top Speed Limiter Removed:<\/strong><br \/>\n155mph (some sw versions are higher) is now removed.<\/p>\n<p><strong>Quiet Cold start:<\/strong><br \/>\nThe car will start when cold like a warm start. You want get the retarded timing, high revs that is used to warm up cats when stone cold.<\/p>\n<p><strong>Gears 1-3 Throttle Limiter Removed:<\/strong><br \/>\nStock and most XXX tunes have a 50% throttle limiter upto 5k in the first 3 gears. Even though you go full throttle, the throttle body only opens 50% to 5k.<\/p>\n<p><strong>Cold Oil temperature limiter Raised:<\/strong><br \/>\nYou will only get the full revs when oil temps are upto 70 degreesC.<\/p>\n<p><strong>Secondary Air Disabled:<\/strong><br \/>\nAnother vacuum controlled solenoid that can cause any issue with any vacuum controlled solenoid(flaps, exhaust flaps, airbox flaps).<\/p>\n<p><strong>Manifold Flaps Disabled:<\/strong><br \/>\nWhen the inlet manifold is deflapped we disable this operation so you will never get any more manifold flap codes or limp mode because of flap play.<\/p>\n<p><strong>Exhaust Flaps Mapped for Sport Mode:<\/strong><br \/>\nOn the stock map the flaps will open and close depending on driving, even in sport mode they will still randomly close.<br \/>\nWhen Mapped in non sport mode the exhaust flaps stay shut all the time apart from above 5k rpm. When in Sport mode exhaust flaps are open all the time.<\/p>\n<p><strong>Linear throttle Reponse:<\/strong><br \/>\nWhen mapped and in non sport mode the throttle response is more linear &#8211; more like an old skool throttle cable so 20 % pedal position is closer to 20% throttle position. This will make driving slowly and pulling away easier with less kangaroo effects. This exaggarates the oe feel from non sport to sport mode after tuning, but both modes have exactly the same power with 100% throttle. Sport mode throttle response is unchanged.<\/p>\n<p><strong>Left Foot Braking:<\/strong><br \/>\nOE when you touch the brake pedal with throttle still applied it will cut the throttle. Left foot braking is now enabled so you can use the brakes and throttle at the same time, when you are rallying or tracking your RS4!<\/p>\n<p><strong>Cat Check Disabled:<\/strong><br \/>\nFor precat deletes, race cats and decats that do not pass oe cat check. This is disabled. With precats and racecats the car will still pass an MOT.<\/p>\n<p><strong>Fast dual ECU data Logger:<\/strong><br \/>\nWe patch the 2 ecus so you can use VehiCAL data logger. Now you can log both ecus at the same time and for example we log 38 variables at 33 samples\/sec on both ecus at the same time(76 variables@33samples\/sec. With one run we can log everything we need to see how the car is running. VCDS only logs 1 ecu and 12 variables at 7 samples\/sec.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-18 fusion_builder_column_1_2 1_2 fusion-flex-column\" style=\"--awb-bg-size:cover;--awb-width-large:50%;--awb-margin-top-large:0px;--awb-spacing-right-large:3.84%;--awb-margin-bottom-large:20px;--awb-spacing-left-large:3.84%;--awb-width-medium:50%;--awb-order-medium:0;--awb-spacing-right-medium:3.84%;--awb-spacing-left-medium:3.84%;--awb-width-small:100%;--awb-order-small:0;--awb-spacing-right-small:1.92%;--awb-spacing-left-small:1.92%;\"><div class=\"fusion-column-wrapper fusion-column-has-shadow fusion-flex-justify-content-flex-start fusion-content-layout-column\"><div class=\"fusion-menu-anchor\" id=\"MAPOPTIONS\"><\/div><div class=\"fusion-title title fusion-title-15 fusion-sep-none fusion-title-text fusion-title-size-two\" style=\"--awb-margin-bottom:10px;--awb-margin-top-small:10px;--awb-margin-right-small:0px;--awb-margin-bottom-small:10px;--awb-margin-left-small:0px;\"><h2 class=\"fusion-title-heading title-heading-left fusion-responsive-typography-calculated\" style=\"margin:0;--fontSize:30;line-height:1.2;\">Map custom options<\/h2><\/div><div class=\"fusion-text fusion-text-9\"><p><strong>Rear Lambdas disabled:<\/strong><br \/>\nThese can be deleted &#8211; for custom exhausts.<\/p>\n<p><strong>Crackle:<\/strong><br \/>\nOn overun and with clutch pressed the car will crackle.
