What is the difference between Stage 1 and Stage 2 tune?
A stage represents a set of upgrades fitted as a set. As you might expect, a stage is how far you've gone with tuning part of your car. Stage 2 represents a more tuned car than stage 1. Where things can get a bit confusing is that what each “stage” means can vary from car to car, and even from tuner to tuner.
A stage 2 tune involves fitting a turbo-back exhaust on turbocharged vehicles or a cat-back exhaust system on non-turbocharged vehicles. In either case, these systems are designed to improve airflow from the engine. They are also well-known for improving the sound of a car.
Stage 1 Tune up to 549 HP, Stage 2 up to 585 HP, Stage 3 up to 613 HP.
Stage 1 = chip tuning / tuning box. Stage 2 = Stage 1 + downpipe, intercooler, sports air filter, possibly upgrade turbocharger / upgrade compressor kit. Stage 3 = Stage 1 + Stage 2 + engine reinforcement, complete exhaust system, modified intake / air flow.
You can expect to spend around $200 to $500 on stage 1 modifications and $450 to $850 on stage 2 tunes. In addition to stage 1 mods, stage 2 includes induction kit mods to increase airflow. Moreover, a turbo-back can be added to improve airflow from the engine.
“A Stage 1 remap for VW-group cars, or most diesel, in fact, is the least you can do. You'll typically get 20-30 per cent more power. Prices start as low as Rs 20,000 for a remap, and can go up to Rs 1.5 to 2 lakh”, he says.
Stage 2 tuning doesn't typically have the same level of gains – you can realistically expect a further 5-10% increase in power and torque.
Stage 1 implies a modest power/torque increase over stock. The state of a car after another round of modifications. Typically, stage 2 cars are fully bolted with a tune targeting higher torque and power, plus optional forging.
Most Stage 1 type modifications are typically in the +10-15% power increase over stock. Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination. A typical Stage 2 has generally +20-25% more HP than stock.
For a general stock car (i.e. no additional performance parts), a tune will boost your hp by 10 to 15 percent. What's more is that if you've added performance parts to your vehicle such as cold air intake, exhaust, or turbo, the hp boost you gain from tuning may be as high as 50 percent more!
How much HP does Stage 3 add?
Stage 3 takes horsepower output to 248 horsepower on 93 octane fuel and to 260 horsepower on 100 octane fuel. In addition to the power increase, you'll also get an adjustable rev limiter and calibration for a 50-shot of nitrous (nitrous kit not included).
The M133 has so much more in it than Mercedes- AMG would have you believe and a Stage 1 tune. (which is easily reversible) is a perfect way to dip your. toes into the world of automotive performance.

Will remapping my car make it louder? No remapping a car does not make it louder. The car's engine may act differently producing more RPM (Revs per minute) at different and producing more power but does not make it louder.
A Stage 2 performance upgrade is a cam change upgrade. In any engine, the cam drives the valves and the valves open to allow air in for combustion. The kits for improved lift, duration and timing focus on either torque or power upgrades. The Stage 2 upgrade delivers up to 30% more horsepower and 10% more torque.
APR Stage 2
This simple upgrade requires an upgraded exhaust system and intake system and no other engine hardware modifications and produces 270-283 HP with 319-350 FT-LBS of torque.
That said, Stage 1 is very safe. There's plenty of people that have high mileage on Stage 1 (and Stage 2) tunes. Maintenance is far more important to longevity than a simple Stage 1 tune is. Take care of your car and you'll be fine.
Stage 1 tuning mods are simple and fitted in isolation. Stage 2 tuning mods require additional parts to effectively work. Stage 3 tuning mods are generally motorsport only and not usually road legal.
Stage 1 Tuning
Designed for a standard and unmodified vehicle with no hardware upgrades. A Stage 1 Remap increases power and torque while also improving fuel efficiency. Removes flat spots and gives a more responsive drive without compromising reliability.
A full tune up can run you between $200 and $800. As noted above, the cost of tune up varies depending on the cost of parts and labor where you live.
Spark plugs and wires can be replaced for $40-$150 or more for a basic tune-up, but a standard tune-up can cost $200-$800 or more. This may also include oil changes, a fuel system inspection, and computer diagnosis.
Can you go straight to stage 2?
While many car owners start with a stage 1 remap before progressing to stage 2, this isn't necessary, and you can theoretically take your car for whichever stage of ECU remapping you want – when trying to find the best remap company in your area, try asking garages if they can do a stage 2 or 3 remap on a stock car.
Yes, catless downpipe is required for stage 2 flash tune.
Make sure your engine oil is full, and bring extra oil with you at the time of the tuning appointment. We have limited oil in stock at the shop. Make sure your coolant level is full in the engine/coolant system. The cooling system MUST be bleed before the tuning appointment.
Stage 1: This refers to the early stages of vehicle modification whether for economy or performance. A Stage 1 remap could be a simple economy map to gain more mpg, or more commonly, drivers want it to enhance their car's performance.
stage 1 – the cancer is small and hasn't spread anywhere else. stage 2 – the cancer has grown, but hasn't spread. stage 3 – the cancer is larger and may have spread to the surrounding tissues and/or the lymph nodes (or "glands", part of the immune system)
