RPMNORTH shop car dyno results after tune up
The shop car that we bought came to us with 60,000 miles and when we first dyno tested it we made 408 horsepower and 440 ft. lbs. of torque. We decided before we do any upgrades to the car that we would get the car to it's peak performance in stock form.
In order to do that we gave the car a full tune up using the parts that we feel work best in the car. We did a transmission service which included fluid and filter and changed the leaking electrical plug (I recommend doing this every 30,000 miles for years of trouble free service). We did an oil change, changed the belts, plugs, coolant service, filters and a carbon clean.
We just got back from the dyno and the car made 420 horsepower and 462 ft. lbs. of torque. This is a totally stock engine that has not had any high performance parts installed yet.
There are so many people that do not pay any attention to the factory maintenance on there vehicles and they are leaving a lot of horsepower on the table. I hope this shows everyone that the factory parts do wear out and when you renew those parts there is big room for improvement. Every tuner will have there own idea of what parts are good and what these motors like, we are pretty happy with what we found and the parts that we chose to use. 12 hp and 22 ft. lbs. of torque is pretty damn good considering we have not done one upgrade yet.
Pay attention to your tune up. Do a major service every 30K, it does make a difference.

Really great post RPM!
I never really thought of that (taking care of housekeeping on your car before modding) until I replaced my MAP sensor and the car perked up dramatically.

Nice numbers Craig! Looks like my baseline numbers before we started modding the beast.
