What Psi to Tune to?

[imagine3163]

I'm taking my car to be dyno tuned in the near future and I was wondering what boost you guys think the car should be tuned at with my setup. The car is my DD so I need it to still be reliable. I was thinking probably not much more than 18psi since tuning is limited with the safc, but I am definitely open to suggestions!

Is it me or do I not see a 255lph fuel pump or AFPR in your mod list? Not very familiar with the SAFC, but if you get a logger you can dyno tune and turn up the boost until you see knock. I don't think you currently have the proper fuel mods mentioned above to turn up the boost to as much as 18 psi.

Forgot to add those in there...its a Walbro 255lph and Aeromotive AFPR.

daily driver.....I'd say you'd be safe with 20-22 psi. I used to run a similar setup and i ran 22-25 psi everyday no problems.

Basically turn it up until you start to see knock on your logger. I think the 750's with the SAFC will be the limiting factor on what kind of boost you can run. Most don't recommend over 650's with the SAFC as larger then that requires so much compensation, that you timing gets advanced too much, leading to knock at much lower boost levels. Ideal on the 3052 would be 20+ psi, but not sure you'll be able to do that with the SAFC, DSMLink on the otherhand would make it more then doable. Personally I'd run 22 or so psi daily, if its possible with your setup. This is what I run my 3052 at & was just at the track this past weekend, so threw a bottle of NOS octane booster in with my pump gas & was able to run 25 psi without knock, & the 3052 loved this boost

Yeah the SAFC is pretty much the limiting factor in my setup right now. I am currently working to get some money together and will go for dsm link. Thanks for all the help guys!
