lol, i'd like to correct myself if a ka is a hw-5, i didn't see any info on a ka so i was going with past experience of "ka and sr mafs are interchangeable" so if an sr wants hw-6, then ka should also.

i did the neo in that red s14 you tuned this morning that made 264 rwhp, he told me you said the same thing i told him about the stock maf and not being safe past ~265 lol that was right on the money, i had his boost controller turned all the way down and the thing still spiked to 16-15psi hehe
