why only 18 psi wtf???

 

most guys running that setup shoot for 23 psi or so on pump , unless your on supercrappy 91 octane fuel you should be able to squeeze out another 4-6psi

 

On my stock turbo I use to run 27 psi all day long..

 

Im running 93 oct, I wanted a safe tune but i guess 22psi wouldn't be too bad.

 

25 psi and your still safe..

 

yea 24-25 psi and ud b happy and safe

 

yea i made over 320 on my stock turbo on a dynojet

 

That setup should be 330-340 at 24-25psi on 93. Possibly a little higher even. The best I have done with those cams/combo is 354.

aaron

 

You need more boost. Stock boost is 19.5lbs, and your lower then that

 

25psi is a safe tune. Turn it up man there is nothing to worry about.

 

that is what i was thinking. OP depending on the fuel in your area you can go from 22-27 psi yielding much better gains / results.

 

I run a similar setup to yours (9.8 and hks 272) and ur definitely good for another 40hp if u bump the boost up another 4-5psi. Especially w/ the spoolinup ur safe to turn it up. I made 330 on a DJ on the 9.8 with hks 272s at 23 psi on 93....but it was tuned by the master Ivey

 

I am close to you in mods, but with stock cams. So you can look at mine to see the differences. I am runnin 93o boosting to 24psi with a taper to redline down to 19psi. With the following mods I put down 283/282 in a Mustang in ground

Evolution DYnamics Tuned 24psi taper to 19psi
Evo VIII 10.5 Turbo
Greddy Evo2 Catback
Perrin DP
Test Pipe
Injen Intake
Injen UICP
Injen LICP
Walbro 255

Also notice the dip from 3900-4600rpm in torque. I hit a 3 count of knock there and it pulled timing (it doesn't do that on the road, but it did on the dyno :shrug: ), so with a tad more fuel to prevent that I could have a little more torque:

 

What EM are you running on this set-up?
