i have a 2004 mazda rx8 4speed automatic. i have a leak at the header and deemed it pointless to put new stock parts on a car. i have a racing header and cat delete i need installed and its about a 2 hour job. i lack the proper equiptment to do it my self and have no one to assist me. i was wondering if its a task that you can do and what to cost of the services would be?

I wanted to know how much you charge to do the APR stage I tune on my 2012 gti. I believe i buy the program from APR and you can install it? Thanks.

Hello,
I am an owner of a 2010 Mazdaspeed3 and there were a few things I was looking to do to my car and was wondering if your shop performed them. One I am interested in blacking out the taillights on the car. Secondly I am also interested in painting the brake calipers. I would appreciate more information on these two services if they are available through your shop.

I currently have a 2012 Acura mdx – I’ve owned several high performance autos and am looking to upgrade the performance on the mdx fairly significantly! Probably including lowering the car approx. an inch or slightly more. I knownit’s not your typical auto to upgrade, but I was interested in seeing if you had any ideas or have done previous work on any mdx’s – I’m interested in getting your response.
Thank you,
Robert

HELLO, I HAVE A 12 AUDI A4 QUATTRO. IT IS A LEASED CAR AND I WAS TRYING TO GET MORE INFORMATION AROUND HAVING A STAGE 1 TUNE FOR THE CAR? I WAS CURIOUS IF IT WOULD BE OBVIOUS TO THE DEALER FOR NORMAL SERVICE IF I HAD THE CAR TUNED? ALSO I WAS CURIOUS ON THE RELIABILITY AND COST.
THANKS IN ADVANCE,
FERNANDO

Fernando, thank you for contacting us. The APR software is visible to the dealer if they look for it. However, during routine service the dealer typically does not check for software. Also, if you choose to purchase multiple programs you can choose Stock programming as one of your programs so that you can switch back to stock programming when returning to the dealer. This way the dealer cannot feel any difference in how the vehicle drives.
APR’s software is highly reliable. It maintains all OEM and Tier 1 safety measures so that your vehicle and motor last as long as possible. I personally have APR software on two of my vehicles, a 09 GTI with APR Stage 3 and an 12 TT RS, and both vehicles were flashed within 500 miles on the odometer.
The cost for software depends on how many programs and options you want.

A single program is $599 but if you want to be able to switch back to stock it would be $149 extra. If you want to be able to lock the program in place so that the dealer cannot change it then it would be $59 extra. Audi added ECU encryption to many of the newer ECUs so the ECU does have to be removed to be bench flashed. The cost for that is $150.
Please let me know if you have any other questions or would like to set up an appointment.

I bought parts from xlr8 for my 07 TL. I Highly recommend the Xlr8 Coilover kit. The whole car feels different from eibach springs that I had on there before. Everything came on time and in perfect condition. The service is very good and prices are even better. Josh helped me in the right direction to go with the intake, the camber kits and also the engine mounts. If you ever call in ask for Josh. I thank you guys again and im extremely happy with all the parts i have installed on my car. Ill be seeing Xlr8 soon for more upgrades.
