did a 14.7@94 with a 2.24 60', stock no track prep. If I get my 60' down to 2.1, I would be in the 14.3 range
I think you keep you're engine free of carbon with all you'rre highway driving. If I get my rockers installed and drive to LA, a good 900 mile drive. I'll run her at sea level. Shell get high 13'* even without a DHP. I'm sure shell be carbon free by then.

you can do:
headers
intake
Throttlebody
smaller pulley
colder plugs
intercooler
rockers
you can use the stock catback with headers and should be fine. you just need to scan and see if you are getting KR

Alright guys I will need help with understanding all this. What do you mean by colder plugs, I have been around cars for a while but not these new ones. Where can I find the colder plugs and where can I find a smaller Supercharger pulley??? Would I also be able to put a cold air intake on it???? This is all new to me since this is the first supercharged car I have had.
Another question I was wondering if I did a cat back exhaust would I be able to make it dual exhaust??
Thanks guys I need all the help I can get.

Colder plugs: spark plugs have different heat ranges, the more post you have the more detenation you get (KR). putting in colder plugs allows you to run more boost.
check out www.zzperformance.com www.intense-racing.com all of them sell cold air kits along with plugs and most parts will need
i am sure you can make it a dual split exhaust although sometimes that makes more back pressure at the split. you can do anything with time and money.

NGK tech-talk faq is in Techinfo for the plug question.
Only a GP FWI intake will work on an H body. A CAI setup will have to be modified from the GP application, or totally custom like most of us do.
FWI is not preferred in the 87-99'* due to the configuration of the fender skirting. It'* a good option for the 2000 and newer though.
