x a billion lol. Put the stock pulley back on or buy headers and install them then tune and scan. Trust me you will feel the difference

exactly, the computer has to be umm adjusted to do that, just because a smaller pulley is on it doesnt mean it will be faster. The computer might see the increase in boost as engine knocking and can pull timing a lot of timing. just depends on how many degrees of KR you have. my car stock was putting up 6* of KR and when we had that tuned and decreased the KR it ran SO MUCH BETTER!

ebay for headers. and read the kr sticky it will explain alot of things. put the stock pulley back on

Look into a mail order pcm from zzpeformance.com, but I think a few people have had some problems with theres recently, so intense might be better at the moment, or DHP

you can buy a pcm. intense or overkill. or you can by a tunner and tune it yourself. if your not going to tune it yourself i recemed overkill or find someone close to you with a tunner and will tune it that has a gtp. i wouldent let just anyone tune it

Well yeah lol

do they work on gm 3800 engines??? if not i wouldent trust them. not all tunes on all cars are the same.

Make sure to look at ebay for headers, they are CHEAP!

Depends how much are you willing to spend? I know Riley picked some what look to be good ebay headers. eBay Motors: 1997-2003 PONTIAC GRAND PRIX 3.8L HEADER 1998 1999 2000 (item 260330100189 end time Jan-08-09 16:27:00 PST) but there are slp, s&s and ZZP headers

Well yeah fish thats true, but Im assuming he would ask them if they can dyno it or not lol

The Pacesetter ones?

the ebay headers work fine. there is a few people on here that have no problem with them. at zzp your just paying for the name

x2 i ordered headers last night off ebay for 236 shipped

No ZZP has their own set of headers ZZ Performance

Edit: I linked the headers he ordered further up the page
