my car was tuned to 14 psi ,on second gear i got 8psi,
third gear 11 psi . and 4 th gear 12 psi. BUt the tuner said that i was gettin 14 psi. Is this right. or is the tunning to unrealistic for street driving.

 

what????????? please re-write your above statement into something that contains full thought, instead of fragments. Because we can't really help you without more specific detail.

 

okay on 4th gear i get 14 psi... so does it mean its normal for me to get less boost then when im on 1st and 2nd

 

Yes, your highest load will be a 4th gear pull so they tune it for however much boost you get in 4th. They do this because if they tuned it for 12 which you might be getting in 1, 2, and 3...you might detonate when you hit 14 in 4th.
