Hi I have an Infiniti G37x 2010 i have fast intention high flow cats and stillen cold air intake is it worth getting my car tuned will I see atleast 20whp in gains or more?

 

Are you done with your mods? If not, then no.

Every car is different and every tune/tuner is different too. Some ppl have seen a 20 whp gain from just tuning their stock setup while others have seen less with modifications in place.

You got the wallet and a good tuner? Sure go for it

 

Absolutely get tuned. Just dont' tune until you're done with your engine mods.
Tuning really wakes up the car.
