I ordered one for my SRT6 today. I do hope they are as easy to fit as some of you have said. Any tips, gratefully received as I don't have a magnet...will this cause me a problem ?

I went for the BDD451A2 as it is supposed to be better for the SRT6 (AMG) as it is marginally less aggressive than the BDD451A.

I wish we could get them in the UK for as cheap as some of you have. I got a new one for £179 in the UK delivered in 24 hrs.

 

Simon,

Ignore the 'how to' regarding the magnet.

When you look in your car, look where your right foot goes. There is a trim panel that will extend from your right foot up towards your knee area.

On this trim panel, there is a vent. The vent has a cam-locking 'screw' in it. If you turn this screw 1/4-1/2 turn counter clockwise, it will come loose. You do not remove the screw all the way. When you turn it 1/4-1/2 turn, it comes loose, and the vent should come off.

Behind this little vent is another screw (zinc/gold colored phillips head). Remove this screw. Now the trim panel can be removed.

You have to flex the trim panel a bit to get it out. This is the hardest part of the removal/install, but still very simple. Just be careful not to over stress it. A little bit of slight flex will suffice.

Once it is out, lay down into your floor board as much as possible. You will see wires connecting to the back side of the gas pedal. A small headlamp or flashlight will help here. These wires connect to the TPS. There is one plug that has a 'push tab' on each side. So, you basically have to get your hand on this plug with your pointer finger and your thumb. Depress the tabs on each side and pull the plug out. BE SURE to depress those tabs. If they are depressed, you should be able to pull the plug out without much force. After it is disconnected, you simply install the sprint-booster in it's place, and connect the factory wire to the end of the sprint booster. Basically, the sprint booster is mounted in-between the existing original wiring.

Re-install the factory plastic panel - re-install the screw - re-install the vent - re-tighten the cam-locking screw.

Done!

This literally took me less than 3 minutes. I am not a small guy, but not a huge guy either (5'11" 185 lbs), and I have rather large hands. I didn't have any trouble. If you are not able to get down on the floor board very well, or your hands are too large to maneuver the electrical plug, find a small child who can take directions well.

I did not unplug my battery and 'reset' my ECU. Some people say they had to. Mine worked just fine without doing this...

I also went with the 451A (not the A2), and it doesn't seem overly aggressive at all. I'm anxious to see how you like the A2.

Where did you order your sprint booster from? Is there a particular brand that's better than another or are they all the same?

 

They are all manufactured by the same people. However, there are a few different distributors to buy from.

My suggestion, based on what I've read, is to buy it from the Ebay seller found in my signature (click on the red text next to sprint booster).

This seller is very reputable, has not had any negative feedback with those people on this board who have purchased from him, and gets his product to the US within 6-10 days (and it's coming from Hong Kong). The only delay that he may have is if he does not have them in stock.

I purchased mine used, so I didn't go through a distributor.

If you have the SRT, you can use either the 451A or 451A2 model. The A2 is supposedly less 'aggressive' than the 451A. I have the 451A, and don't seem to think I would want it less aggressive.

what is the sellers ID, i clicked on it and there were none found. i was looking to get the 451A as well as the more aggressive the better.

 

Sorry about that - his ID is Partsexporter.

Here is a link to one of the 451 version, Not 'A' or 'A2'. This one is for a manual tranny. However, if you contact him and he has one in stock, he will make a listing for you.

Partsexporter

If you don't want the 451A2, don't tell him you have a SRT - or he will try to push the 451A2 on you (because the manufacturer told him so).

If you do a search on the forum, there is a response from the manufacturer that says the 451A will function just fine with the SRT. The larger AMG cars (55's, etc) may throw engine lights with the 451A, so they made the 451A2. However, our cars (SRT6) are just fine with the 451A.

Hope this helps.

thanks for the quick response, i'm ordering it this week. are there any others that went with the A as opposed to the A2 route? and have had it w/o any codes thrown etc... thanks.

 

Gatesy,

I did a long and extensive search on that subject prior to purchasing mine.

Here is a post with an email from the manufacturer (Boulekos) saying that the A2 is more geared towards the very High performance AMG engines (not the SRT6 which isn't considered one of the 'monsters').

Read it and make your choice - if it comes from the manufacturer, I'll take his word for it.

Feel free to contact them and ask for your own sake. Let us know what you find and what you end up going with.

Thanks for all the replies. I have read through a few other posts as well re the "A" and the "A2" and as I do quite a few short trips and round town driving think that the "A2" is definitely the best option for me. After all I bet if you floor it they both open to full throttle in the same speed and that most of the difference is in the 1st half of the throttle movement.

I will print of the instructions from ShawnQ as they look really simple, so thanks for help and I will post what the "A2" is like as soon as possible over the next week (all going well).

 

If I disconnect the battery to install this and re set the ECU, will anything else be affected eg emissions or radio code needed ?

 

There is no need to disconnect the battery.

 

Phew ! Cheers. Is it worth doing a throttle reset before I install it ?

 

Definitely!

Did you install it last night?

Any troubles?
