2016 Silverado 5.3 A6 back with some more mods (Nick Willam’s 103 Throttle body and custom 4” intake.)
Customer started having really bad cold start issues around a year ago. This was solved with a new throttle body (all the customer did was bolt on the NW103 and fixed it immediately) These generation of trucks are having more and more weak throttle body issues.
Whipple Superchargers 3.0 whipple on this truck since mid 2023 with a Brian Tooley Racing stage 1 PDS cam.
7 psi of boost
