The Vortex XL will make over 450 HP. You need the standard Vortex. Going to need the HPFP also. And 425 - 450 HP does not require MPI or a LPFP.
That is not necessarily accurate. I was tuned on the XL with HPFP only on 93 and my LPFP is plenty fine. Also in the 450+ whp range.I'd also advise against that.
And like @MSH said, I don't think they'll tune it without at least the HPFP. And then when you're doing that process, you'll be told your LPFP isn't good enough. And you'll see the stock PUT being maxed out.
Just do it all at once, right
My opinion is riding the margin of safety with an inadequate fuel system isn’t wise. One bad tank of fuel could ruin you.
Do you have a log to share? I would like to see the redline range requests.
blasphemy
Un-American
This is my second to last revision. The final revision was cleaning up fuel trims a bit and that is it.
To be fair, this is on stock sensors. Swap those out and I may gain roughly another 20 whp from where I am sitting now.
We have similar setups, I'm almost on the verge of getting the sensors and a new tune (already have the A2B brushless pump just not installed yet). I heard its roughly 20-30whp just from the PUT and 5bart sensors, also want to tune for an e40 mix. EQT's boost weather sale isn't helping!!!
I've been on the fence, my power goal seems to be closer to the limit of the standard Vortex. It also seems closer to fuel limits.
This was I was thinking, $100 top-up tuned with lower boost pressure until I upgrade fuel.
