Hi guys. I bought my Srt6 roadster new in 05 and have been very happy with it. I’ve taken it to the track and it runs 13.1, 13.2 consistently.

Now I’m looking to do some mods. Here lies my problem: I LIVE IN AUSTRALIA! It’s like living on an island in the middle of nowhere that’s about 10 years behind the United States in terms of technology and car modes and have nothing available to us.

I'm looking to get the air intake and ASP Pulley Kit from needswings shipped here.

My problem is there is no-one that can do any chip tuning here and am not keen on sending my ECU to the states.

Have any of you guys installed the pulley with no ECU tune?? And if so how would it run? Any complications?

Over here I can get the upgrade from powerchip but not sure if that’s tuned to compensate for extra boost.

If anybody has any information or suggestions please help me out. People in the states are so lucky, they have access to everything...

Thanks guys.

 

I ran my 178 all last summer without a tune.Its not a problem.You just wont get the most out of the car without a tune but you will still feel a big difference over stock.

 

you can install just the cai and asp pulley without needing a tune, the stock tune is capable of handling them both. an aftermarket tune will just make a little more power at that point but isnt needed

 

What kind of gains in terms of HP with the CAI and pulley without a tune?

 

milage may vary from dyno to dyno but should put down 320-350whp. do a baseline dyno in the morning, install the parts and go back for the power pulls in the afternoon after you have put ~ 20 miles on the car. you will be happy
