I drive an evo IX with a K&n typhoon air intake, megan headers, ams fuel pressure regulator, and a single 255 pump. Does that warrant a tune?

 

Warrant. No. Could you benefit from one. Yes

 

short answer is YES, Long answer is any Evo with a stock tune can show gains and more enjoyment during driving from a tune. The factory tune is very rich can be cleaned up in a short time. If you want more details feel free to PM me or Jason@Spec-Ops for more details. I look forward to hearing from you soon.

the typhoon intake isn't a good intake for an evo...you should swap that out ASAP

you should either remove the fuel pump for a stock one or get the car tuned...your car is running so rich with the faster flowing pump it's probably ready to drown in fuel

for more information...see the link posted above mine
