I have the thumpr cam. I like it despite all the bad people talk about it. I have a 3000-3200 stall prolly should have gone a little higher from what my brother says. When I drove it last it had factory TC. It pulls to about 7200 and breaks both tires loose at 45 + Chris@lsxps did a great job of tuning it. pulled an extra 20 hp and like 30 tq more than the tune from speedtek. And it loves the 4.10s
