Power Pack
I have been running this tune/package on my SHO for over a year. Increased performance and fuel economy...never thought you could get both. Lee’s customer support and Luis’ tuning and turnaround time was beyond impressive. Luis reviewed multiple datalogs until deciding the car was running perfectly and safely, making smooth power and shifting on point. They answered any questions and concerns almost immediately and an updated tune was sent within 24 hours. That’s what will keep me coming back.
I recommend this product.

Fantastic Set of Coilovers
High quality parts. Love the fact they're rebuildable and adjustable. Springs came preloaded all I had to do was put them in and adjust the height and damping. They fit just like factory. I was able to match OEM ride quality by setting damping 10 clicks starting from soft. Currently on highest ride height. Only complaint is the fact that the strut tower has to be cut for camber adjustment clearance. I don't care for that so I just left it alone. I actually don't recommend cutting up your car at all. I hope to do more testing in the summer, but so far I'm impressed.
I recommend this product.

Explorer moves!
Talk about something to wake up your ride. All the parts come ready to go as a kit. Everything you need in one kit no searching for extra stuff. East driveway install by the average mechanically inclined individual. Customer service for questions and tune revisions super fast and easy. Lee and Luis are great to work with and will help with any questions along the way.

Excellent Buy For More Fueling
Once you have done all the basic modifications to your Ecoboost, you really need more fueling to keep you running safely. The XDI high pressure fuel pump offering allows you to extend performance far beyond factory spec and keeps your system running efficiently to prevent failure. A must have for anyone planning to go beyond the basic intake/downpipe build package.
I recommend this product.

Excellent buy for the money
Luis tuned my Taurus SHO combined with the Starter Pack and SCT X4 handheld, and wow what a difference! On the base tune I jumped from 13.6 in the 1/4 mile to 12.9, then with downpipes and E30 I'm running 12.4s for under $2000 in total investment. Don't hesitate to hit him up for your tuning needs.
