RennTech Performance Ecu Upgrade For Mercedes-Benz CLA45 AMG 2014-2021

The RennTech tuning module allows the user to change the performance level and gives the ability to set different performance levels running both higher or lower boost compared to delivered settings. This gives you power on demand or economy when you want with smooth torque delivery and performance throughout the entire powerband. This also allows the user to compensate for fuel quality and places of extreme climate or to adjust for higher octane fuels and the added performance of racing blends.

In some cases, we may offer the ability to return the item to us for a lesser restocking fee and then keep the balance as a store credit. To return an item, it must be in brand new condition with original packaging.

                                          We cannot accept a return on special ordered or custom items.

                                          Special Order Items

                                          Some items may be special order specifically for the customer’s vehicle. These items generally require a deposit or paid in full. Once this deposit amount is notified to the customer and they agree to order the special order item, the deposit becomes non-refundable. These special order items cannot be returned or resold. Cancellations are not allowed on special order parts.

                                          AutoTalent DOES NOT REFUND SHIPPING CHARGES. If you modify, install, or alter the item in any form, we cannot accept it as a return. We will not cover any expenses related to the product or installation, and you may be required to purchase a replacement.

                                          ** All cancellations that are requested that are NOT due to items not being in stock or delayed by the manufacturer are subject to a 5% processing fee. When you place an order with us we pay credit card fees that are NOT returned back to us. We will absorb these fees if we do not have the item in stock OR if you agree to the original ETA and that ETA is NOT met. If you decide to cancel for any other reason you will not receive this 5% fee back
