do you have 79lbs injectors or bigger? And i'm sure you know a tune would be good too.

need a little more info than that. you shouldn't need anything more than a tune, and making sure you have the fuel to support that much airflow.

this is of course assuming you have cooling/exhaust/etc

yes i have all cooling mods header,d.p,exhaust, for sure a tune would b needed, just from one response i now know that 79's would b something i need. fuel im running 94 octane and 100% meth if you needed to know that. just wondering if there would be anything else that would yield any more power with the drop in size or if theres anything saftey wise if this makes sense lol

you may want to upgrade your exhaust to full 3 inch downpipe back and 1.75 primaries with a 3" collector.
