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.

 

What exactly is a 'carbon clean"?

 

Sounds like a good Seafoam job. I used to think the stuff was a joke, but then tried it once and it really does work. All of the cars I've tried it on with over 50k on the clock ran noticeably better afterward.

 

It goes under the air filter , like a charcoal filter !!!

 

Air filter or pour-into-the-motor cleaner? It sounds like we're looking at two different things here. After looking at a brief description of the Seafoam product, I would think that an oil change would be in order after using it. Maybe RPM can elaborate?

 

I don't really know what seafoam is so i can't comment on that product. I used a Motorvac machine on the car.

 

Seafoam is for carbed engines usually. You pour a couple ounces into each gas tank and it helps clean dirty carbs for bikes and boats mainly. Haven't heard it used for new FI engines.

 

Thanks for the clarification. I use Techron, but no fuel tank additive can come close to matching a professional cleaning of the injectors and fuel system. The Motorvac must work wonders.
