Doing some street tuning on this 67 Ford with a 3rd gen coyote/t56 mag swap! Oem Ford standalone control unit kit. Looks great parked next to the 87 C10 LS3. Which one would you drive?

2000 BMW Z3M in the shop this week retiring the factory ecm in favor of a plug and play Megasquirt 3 Pro. After it received a quick tuneup up on the S52 straight six it was loaded on the dyno to be dialed in. With the Vfengineering supercharger kit we saw a peak of 259/251 on 93. We love these plug and play Megasquirts since they make it so simple to bring modern electronics to many older machines. If your car is modified and one of the few options supported get in touch for us to do the conversion! DIYAutoTune.com

15 WRX made 281/311 with an Extreme Turbo Systems Intake/J Pipe, Cobb Catback. Great example of how warmer temps affect these cars on the dyno. On a cool day we typically hit close to 300whp with simply an intake. On a warmer day the factory Intercooler with lower those numbers substantially
