After 25 years with this Supra and MANY shops for modifications (From MD to NY) I'd have to say that ISP is hard to beat. Yes, there are some really good shops around with extensive knowledge of the 2JZ platform, but when hp/cost comes into play, ISP Racing has them beat.

Worst experience I've ever had. Went here after having couple friends go years before me and spend tons money and built some badass 2jz Supra's.. Brought my car to have tons issues, never got my tune completed, and left with a none drivable car and no refund. Never left a negative feedback and moved on. Came back to leave a negative because all of his work keeps haunting me over and over again. The last straw was his brand new fuel lines he installed are now leaking all over the place. Spent well over 12k with him to have all the work basically needing to be redone and replaced.Owner was a cool guy but work was not up to par and when you contact him with issues you get excuses.

Dropped over 10k to have most of the work completely redone. Was not going to leave negative review, but now the brand new fuel lines he installed are leaking. Every time I thought all work he did would stop haunting me it hasn't. Literally worst experience I've ever had. Now over 50k invested in car all work done here was wasted time just to have to redo it all.

When I upgraded my truck engine from a 5.3 to a 6.2, I needed to have it retuned. Peter went out of his way to help, even letting me come in on a Sunday, when they were supposed to be closed. My truck is not used for racing, but I needed to optimize it because I use it for work around my property, and for trailering. They did a great job!

They couldnt tune a modded BMW 650i. Guy answering the phone has no customer service skills. Maybe keep him in the shop not answering calls?

I happened to be buying a high performance car near Peters shop so I decided to stop in and let Peter take a look. He did not disappoint, besides being the nicest car guy ever he really knows his craft. We did a compression check among and few other things. I really wish his shop was near my parts so that I could come back with a anything in the future. If you're in the DC area and need anything performance, Peter and his shop Infinite Speed and Performance is what you're looking for.
