Today I had my first remote tune session with Doug at prestige motorsports to check everything. As i mentioned before they are a pleasure to deal with, Doug FaceTimed me and talked me through linking up computers so he can access my computer. I went over everything on motor and found no exhaust leaks prior to session. Once he was logged on and I started car he Immediately shut the motor down and told me i had bad exhaust leak,computer was dumping 50% more fuel than needed to try and correct itself. He than shut off the o2 sensor and car was perfect. He than told me how to pressure test exhaust with a shop vac and soap/water to find leaks without starting car and it worked lol needless to say “slip fit” is no good as a few mentioned to me previously lol. Its crazy what 2 small pipe leaks can cause. Doug told me to fix leaks then call him to link in again and check. Their engines, customer support, and knowledge is amazing.
