I love this!! I'm very jealous because I really want to add boost to my 55, but not in the cards right now. As for the boost through a Holley TBI I can't speak, but the software side it's 100% possible. Not only that, it's quite easy. I think that the stock Sniper fuel injectors are good for around 450 HP on an N/A vehicle, so the boosted would likely be less. More like 375-400, but is likely less than your target so you should be good there. You'll need to figure out what MAP sensor is a direct fit in the TBI and can read up to 2 Bar. You'll also want a beefy fuel pump, but you likely won't need anything more than a 255 lph since you are not looking for lots of boost. On the tuning side, you need to re-map the VE and Spark tables to account for the added boost which reads in kPA. 100 kPA is atmosphere, and 200 kPA is 14.7 psi, so you'd want to update the VE and spark tables to read from zero to about 150 kPA. You'll also want to do some reasearch on what AFR you want to run. I think generally you'd want to be around 12.5 at 100 kPA and bring it down somewhere in the 11's at full boost. Depending on how the motor reacts though, you could lean that out. Selecting the AFR is a hugely critical step in these "self-tuning" ECU's. While it does have a learn table for your fueling, you need to populate the AFR, timing and other variables. I'd probably just pick a 5psi wastegate spring and let the computer tune your fuel tables after you set AFR. Sounds like a really fun project, and I can't wait to hear more about it. Feel free to text me if you have any questions.
