So my MAF just went out. Super rough idle. Rpm going 700-1300 up and and down up and down. Unplugged maf and it’s idle at normal. Just replaced IAC cause I thought it was that. Anyways, since the 2400 is discontinued, I have no choice but to get the 2600. Will I need a retune if it’s tuned for the 2400? Or is the 2600 just the same but more sturdy?
