its a 5.3 with two t3/t4`s 80lb injectors cos3 it runs rich when idling but when it gets into boost around 3600 it starts leaning out gauge shows 16.1 any help would be greatly appreciated here's the tune and a data log

Is FPR manifold-referenced or un-referenced...?
What is measured rail pressure (with FPR reference hose temporarily disconnected)...?
set at 43 raises to 53 unplugged and under boost 64
So FPR is set to 53 psi with reference hose unplugged...?
( an you adjust it to 58 psi (with reference unplugged)...? )
Did you use 53 psi to calcuare IFR table for "80 lb/hr @ 43 psi" injectors...?
No i used 58
So FPR is set to 53 psi and IFR in tune uses 59 psi...?
I had it on 58 i turned it down to see if it would lean out the idel
I put the right numbers in for the ifr for the pressure im running its idles and cruises abut 11.5 to 12 afr I cant figure why it doesn't run the commanded afr"s
