Hi, I am new to this site, looks like a lot of fun.

Here's my question:

My intake (manifold) on my 99 GT conv. is crack so I started to look at some performance parts and found the following...

It's a Typhoon manifold (75mm) made by professional-products

My question is do I need to modify the computer of my car once it's installed? Eventually I will upgrade everything to 75mm but right now its stock (plenum and throttled buddy).

Thanks in advance for your help and input.

 

In short, don't get it.. Many people have problems with them.

 

Really ??? Your the first that tells me that...

Any other suggestion ?
