There's been a lot of posts in the forums in regards to retuning the ECU. Nearly all responses says that its impossible to retune.I just installed the Blitz throttle controller and plan to install the K&N typhoon intake and Joe Z exhaust when it gets in later next week. My buddy whose worked on cars forever said i should get a tuner/programmer to re-adjust air/gas ratios, etc. for all the mods. For you all that have installed similar gear, did you need to adjust anything?
Thanks in advance.
