ECS may have to chime in on this but I thought I read a post that they said they make a couple of changes to the Vortech kit but overall it was Vortech.

Thanks!

To clarify this, on the 5th gen's we both made our own kits, well since we buy their head units they know how many we sold compared to how many they sold and they thought it might be wise to work together rather than as competition. So we worked together on the 6th gen taking our experience into account and their experience as well.

I really enjoyed working with their engineering team and I sincerely feel we have a rock solid supercharger kit at a reasonable price. So all Paxton kits are an "ECS kit" and the Vortech kits are Vortech. Sometimes they ship from here, sometimes from Paxton/Vortech, depends on where it's going and who has what in stock to ship faster.

Both tunes are indeed what I'd call speed-density to account for the screwed-up MAF location that this kit uses.

Keep in mind if I send a file via email or mail order I have to keep them very conservative, the last thing I would ever want is to hurt your engine.

We have had few guys break 900 rwhp with a 1500 now, the DI engines seem to pull more power per lb of boost.

Before I bought mine, the ECS guy was saying the kit was good for 800hp. However he later revised his estimate to 700hp, probably due to the drive system rather than the size of the supercharger. Vortech does list a drive upgrade now, for over a thousand dollars.

We always prefer to under promise and over deliver than the other way around, but as I'm sure you have seen from Vengeance they have made some pretty impressive numbers from the base kit.

See above.

One last thing, to increase boost on your kit all you have to do is switch your cog pulleys. Put the 32 on the jack shaft and the 30 on the head unit and just like that you're making 8-9 lbs of boost.
