ok here is what should be done after you get your base line.
1) make sure it has 91 or higher fuel in it. never know if someone put regular in
2) since your set on it put your intake and 180* tstat in.
-minimal cost since you have planned for this.
3) get a new set of plugs. if you have more then 5* of KR i'd say drop autolite 605's in and gap at like .055
-$15 or less
4) if it still has the Ubend in the exhaust have it removed. you can either buy a new 2.5" or 3" DP or take the car to a local shop and have a new pipe welded in with a O2 bung for the rear O2.
-$30 at a local shop to $150 for a new down pipe shipped to you.
this quick list would be what i would do if i were keeping it mostly stock. personally i would just get some Speed daddy headers and upgrade the exhaust all at one time vs spending $150+ on a down pipe.
