Was the 12.2 a/f ratio with the stock tune or a diabloSport canned tune?Took my car to the Dyno today. The car is almost bone stock, it has an AEM cold air that picks up behind the front bumper and has a complete Solo Exhaust. Now I have a slight odd ball on it because it has the auto Exhaust on a manual car. I was one of the testers for Solo I believe this was the second set of R/T Cats they built, the car has 7,000 miles with no tuning. ABSOLUTELY NONE we didnt even buy the diablo till last week not once did we see the CEL. First pull was with the car as it has been driven for the last 7,000 miles. (I do not have the dyno sheets right now but will post them early next week). On the first pull the car made 345Hp and 366Ft-lb. The air fuel ratio was at 12.2 so to those that are worried about this DONT BE. When the tuning was done the car was at 362Hp and 388Ft-lb. I took a video and the sound wasn't as bad as I thought it would be but I will try to get that up when the Dyno sheets are posted. There was a guy there watching and he had a blown 2000 Vette with a magnaflow exhaust he commented on how good the car sounded then I told him how quiet it is on the highway he immediately took down Solos name. Thank you Solo for your customer service and the opportunity to be a tester for you.
