GoodSpeed Performance

Worked with Nick on a Stage 1 APR Tune for my 2021 Porsche
Cayenne Coupe. Excellent service and communication. The tune is great. Def feel the xtra HP and torque

I highly recommend this place. The staff is friendly, and knowledgeable.

I had a question about my 2007 Mercedes 550 cabriolet about tuning, and they sent me a written estimate via email. I definitely recommend this place.

I 100% recommend GoodSpeed Performance to anyone wanting to have work done on their cars. The team here made my very temperamental Subaru actual usable here in the valley during the heatwave.

I have been going to GoodSpeed Performance Lab for over seven years now. During that time period numerous performance upgrades (from 585 HP to 900 HP with 1050 ft. lbs. of torque) and other services were performed on my 2017 Mercedes Benz CLS63 S without any problems noted afterwards. Jon is extremely knowledgeable in his field. All the vendors he uses are top notch and his fees for the work performed are very reasonable. GoodSpeed Performance Lab, in my opinion, is most likely one of the top two best aftermarket speed shops in Arizona.

Thank you to Jon for turning my 911 turbo S into a wicked beast! The car is truly transformed. It’s insane and so much fun! Anyone with a Porsche that wants to take the next step absolutely give Jon a call. He will help you through every step of the way. He’s meticulous and his years of knowledge really show when building a complete cohesive package. Thank you again! Amazing!
