I know of two cars they have blowup on the dyno. Also a buddy of mine wanted me to help him with some fuel tunning on his honda(turbo upgrade) They had it detonating on the dyno with a 02 reading of 12.35 and were pulling fuel out like crazy. If you are looking for dyno tunning you have many choices Atlanta chassie dyno(Very good) Tunned Performance (Dynolab for you oldschoolers) they do all the bigg power Supras very good guys also Balenced performance who specilizes in Z performance these guys know what they are doing on a Z like nobody I have every seen. For anymore info email me but please dont bring your baby to Engineered they are a hack shop.
