Hey I have a 2009 fg turbo , now I've got a 4 inch 4 inch high flow cat to 2.5 cat back from xforce was just the 2.5 kit , had injectors done 1000cc , fule pump and reg , intercooler , bigger rare housing and flapper and port on a new garrett 50 stock turbo ,had it tuned 302kw at 580nm , but since the exhaust has been on before tune nothing but issues , won't stop going limp mode some times lasts 10 mins some times lasts 5 secconds , had codes showing for waste gate close failure and a 02 code . With the new acuator and turbo thought it'd of solved atleast the waste gate issue  ,  any ideas

well, the 'flow' parts of the exhaust like the dump or cat you need a tune to suit... can do a cat-back without changing the tune... but in the OP's case, absolutely needs a tune to suit.

at least the fueling issue should be easy to diagnose on a dyno and/or at a tuner. If the tuner can't at least point you in the right direction mechanically or tune-related then I wouldn't be trusting them to tune my car going forward.
