Just want to say that:
1) I think Greg (Demon SVT) has done a really good job of explaining & documenting stuff. It may not be on his webpage but I have seen more dyno results, MAF airflow & spark advance graphs, track documented 1/4 mile times from him than just about anyone else. 95% of the rest on here talk about only "ass dynos"
2) The guy is clearly doing something right. He was making 187/169 with precats before playing with the intake manifolds/headers and picked up another 2.5 MPH in trap speed since. Thats just not bad at all....
3) I think Greg has spelled it out pretty well "its not for everyone". Removing butterflies WITHOUT the custom spark & fuel calibration, extra Extrude Honing, port matching, wide open exhaust, etc, may SUCK BIGTIME and warranty is toast. I think he made it pretty clear on several occasions.
4) Terry is still an automotive master, "king of the Duratec", and I really do not think the oppinions of these 2 guys sound that far appart...
That is all, CEG rocks!
