Map 5 may leave a bit out on the table.

put it on Map 1 and you'll shit brix.

Map 1 is super safe and you should see @ 13.5-14psi.

Map 2 will be @ 15.5-16.

When you say map 1 13.5-14psi is that at high rpm? And would it hit 13.5 psi in first at 6000rpm?

Thats probably what it is. I broke one of the vaccume nipples off of the stock diverter valves and had to pay for another one. You have to pay to play. This is all part of the experience of modding a car. Look for oil comming out anywhere along the charge pipe or coupleres. Also check around the BOV. If there is oil comming from any joint then there could possibly be a leak there. The aftermarket BOV kits are tricky and can cause headaches if everything isnt done right. Did you put the rubber o-ring gasket from the stock charge pipe into the aftermarket charge pipe? Did you put the metal slider from the original charge pipe into the new charge pipe?

No I didn't put the metal slider thing into the new pipe the one I have has a rubber tub that goes from the pipe into the engine. And they gave me the metal zip tie.

on Map 1, you'll instantly see 13.5-14psi once you go WOT. by redline it will naturally bleed off to @ 10 or 11.

you will NOT see 13.5 PSI in first gear. so much spinning and if you can actually pay attention to the gauge in first gear at redline and make a clean shift into second you have a monster dong, HAHA !!!

Mustang GT's are worthless from 1985-2009 - you SHOULD be able to pull 90% of Mustangs from a dig (obvious exception being the 03/04 4V powered Mach 1's, Cobras and SVT Cobras), BUT, you asked for GT's. all GT's are shitboxes....

don't play with a 2010 5.0 GT or you'll get donkey stomped.....
