Excellent experience at GPI. Made a 700 mile/11 hours trip down to make sure things were done right, and they were! Couldn't be happier with the entire process from communication with James, 1 day engine tear down AND rebuild with Nathan, and of course the VVT cam tuning with Ryan. Definitely can recommend these guys!... See MoreSee Less

Initial impression was great while dropping off my car for modifications. Can't wait to get back a monster. I have the utmost confidence they will meet expectations based on past customer recommendations.... See MoreSee Less

The whole crew at GPI are class acts. From Ryan on the dyno, Aaron pointing the customers to the best $$$ spent to James making sure you leave satisfied. The dyno tuned a twin turbo 2015 Camaro for me and install some other items for safe horsepower...... See MoreSee Less
