Every Saturday till March 1st is a discount winter dyno day. You get 2 horse power pulls and 1 1/4mile pull for $50.00. That is 1/2 off of the normal price. I dont care what kind of car or truck. If it has 4 wheels and 2 that spin we can dyno it. You can also use the wideband 02 senor for a extra $25.00. That is a great tunnung tool for all you SAFC guys. Any questions please let me know. Please call Mike @630-893-5002 to get a spot. We are open from 10-4. I can do around 10 cars a day...[/img]
