The thread title is pretty self explanatory. I currently have a n/a stock compression 5.0 with the mods listed in my sig. Smog equipment was removed before I purchased the car, so I have some codes that need to be cleared and compensation that needs to be made in the ecu. It's had cold start problems since I put it together, and just doesn't run well until the computer goes into closed loop My best trap speeds this past fall with the new motor were right around 103.7, and I was kind of figuring I'd be more in that 106-108 area. I'm looking at probably throwing a small shot of nitrous on this thing in the future as well. I know virtually nothing about tweecers or pms. If someone could direct me to some good educational reading on the subject, or give me some opinions on what you are using, that would be cool. I know that none of this stuff is cheap, but I'm really looking to spend as far below $1,000 as possible. I have friends that are into DSM's and most have screwed around with those SAFC tuning devices, and done data-logging with laptops, so I'd at least have some help. Thanks for any input.
