I ask this because the car sometimes if i hit too down the gas(in 1ยบ gear stopped), the car bogs down, and then recover very slowly, and in hill ups, if i go to 2500rpms in 4th gear the car starts to loose speed. could be because i do not have a ic instaled? :roll:

The ability to turn the boost up and safely run more power.

Get an IC and take it for a proper setup at a reputable, well equiped garage.

Why would you want to run 5 psi if you dont mind me asking?

Oh right. so turbocharging an engine with all the wrong setup, leaving half of the bits off then turning the boost really low is the key to reliability?

Surely a completely standard RS setup would be the best route?

always best to run ic, no matter what boost or power, as its more reliable and power.

but ic wont really help if your in the wrong gear at wrong rev's, as it will bog down, but also is more down to the set up, not ic, as at them speeds a ic wont be doing much.
