Here is Larry Macedo's Magic Dyno results where the numbers are too good to be true and the air/fuel ratio is perfect even though the car now still runs horrible. Look at Dyno Runs 002 and 003 where Premium Pump Gas is used (the last 2 runs were on racing fuel) -
Now look at Dyno Results from Independent Tuners using Premium Pump Gasoline. Wow! The Power Levels are barely above what the car had when it was shipped to Macedo Motorsports in November 2005 when it ran great and had the low 600's in power. Now after two tries by Larry Macedo to tune his own build the power levels are in the low to mid 600's in power. His customer spent $28,000 for that? And to still have a car that does not even come close to running right when delivered in February 2007? But Macedo's Magic Dyno says the power is in the low to mid 700's on Premium Pump Gas. The Magic Dyno also shows a perfect air/fuel ratio...that NONE of the independent dyno tests got. In fact, ALL THREE INDEPENDENT dyno tests showed the air/fuel ratio to be so rich that they went off the scale! Not perfect. The Macedo Magic Dyno also shows RPMs, but again ALL THREE INDEPENDENT dyno tests had electrical problems with the engine build and could not get the RPMs to show up on their DynoJet and had to just use the dyno wheel's speed instead for the graph.



Larry Macedo, the expert tuner, promised "At least the high 700's in power and quite possibly the low to mid 800's" which caused the owner of this Viper to spend thousands of dollars on a defective incompetently installed fuel system and other items required for a car with that much power.
