Like I stated above you really never hear or read on this Board that the Buick (GN) is running real well. The converter issue was really slowing this car down. With a bad converter Brian could only get about 400hp last yr, since then a updated and rebuilt tranny (Husek) and a PTC converter good things have happened. A few months ago it put down 580s on the dyno with no tune but found a faulty fuel pump.. So we went back to the dyno yesterday and on a very good tune and new Weldon 2x pumper 644hp at 29psi. It made more HP with less boost... Just seems like I am always complaining and now its nice to stick my chest out and be a bit proud and seem to be looking for that Mustang or Vett now at lights.....
