if I put an aftermarket intake manifold and turbo manifold with 1 size bigger injectors and have all other boltons will my stock internals handle it?

 

08 TC there are no larger injectors available as a direct replacement, assuning you have an 08 LNF TC. ZZP make a kazillion whp with the stock intake manifold, the aftermarket ones for LNF have proven less than desirable so contact ZZP for advice.
