I have been wanting to do some mods to my new CSVT, and I have been doing a lot of reading about the Diablo Chip (available at CTA Motorsport). I am not sure as to exactly what it does or how much it would actually make a difference. I have already installed a cold air intake. I have read that having the intake will improve the performance. Anyone who has used one or knows how well they work, please let me know if it is worth it.

For some other mods I wanted to change the MAF and and want to know if the 75 mm MAF in the Mods sections, is what I should use. And would I be even better to go all the way to the 80 mm MAF.
