Hey guys, was one this forum years ago when I had my Cayenne Red 98’ z28 a4. Sold it for an srt4 (lol) when I was like 21. Now 10 years later I’m back with my garage queen. Picked up this super clean 99’ SS w 129k for $5500. The motor was rebuilt at 125k, kind of has me worried as to why it was let go. So far it runs great, minus it needing new struts and brakes. Clean title and even has the original window sticker. I have a few questions if anyone could answer them. Did I get a good deal? It also has an aftermarket cam that’s somewhat hard to hear with the stock CME, the paperwork says the model number is 25-TSP22. Im assuming it’s a Texas speed but it’s missing the end numbers and I couldn’t find exactly what cam it was on Texas Speeds site, any ideas on which one it probably is? I was also told it has a stall, the kid couldn’t tell me which one because he buys and sells cars so this wasn’t actually his car. It feels like it might, because it doesn’t have as bad of “dead spots” as my old 98’ a4 but what’s a good way to tell if it actually does have one? I’m assuming to see when the tires start to spin, isn’t like 1200 rpm when the stock converter brakes them loose? If anyone could help me out it would be appreciated!
Yea, stand on the brake and see what it stalls up to. As far as cam it’s hard to say if you can’t find the full sku. You would most likely be able to tel if it was on the larger side. It’s probably a baby cam like 220/224 or something. TSP used to sell a lot of them back in the day.
Ok thanks, yeah I figured I probably wouldn’t be able to find out. But it does sound like it has a bigger lope to it, just hard to hear it from the completely stock factory manifolds and exhaust. Which is why I’m kind of concerned, I searched on here and everyone says not to get a cam without a stall or headers/exhaust. The shop from the paperwork that came in the car is definitely not one around here that specializes in LS motors, I highly doubt it was tuned as it seems to be a small basic no named shop. It seems to run fine tho, should I take it to a reputable shop that works on LS’s and have them see if it is tuned or whatnot? And is it safe to drive without blowing up lol?

If it seems to be running smooth and well then it should be “safe” to drive. People talk about headers/stall with a cam mostly for performance reasons and/or with a big cam it becomes more necessary.
I would definitely buy headers/y pipe for it though!
Stainless headers from Speed engineering are good and affordable. If I were you, I would finish any performance parts aka additional Bolton’s and then get it Dyno tuned
