You can contact Ivans performance via the link below. A lot of us use his map and I think he did a great job. I took mine to a dyno dealer first and wasted my money. I then found out that Ivans would send you the map for a $200.00 purchase so I just bought a tire and he sent me the map. Very fair in my opinion and not sure if anyone would just send you one out of courtesy to him. Good luck! http://www.ivansperformanceproducts.com/
