injector duty questions??? help needed a.s.a.p really

[jib136]

[h=2]my car was mapped by greg with a max boost setting of 1.4bar (350bhp and 380ft torque)
the injectors never hit more then 94% on limitier in 4th.

since then it slowly got worse and worse, it now hits 100% injector duty at 0.94 bar at limitier in 2nd...

as soon as i run it at 1.4bar on full throttle i can only get to like 5k revs before they max out.

would could be effecting this?? boost leak? dying pump? ****ed injector? im not sure what to look for except the obvious.

my spec is s15 sr20det, td05-18g turbo, nismo 550's, z32 afm, walkbro pump (hardwired to battery), exhaust and air filter.

anyone got any ideas what can cause this? i need to get it sorted a.s.a.p as ive got snetterton booked for the 30th.

thanks [/h]

are you running a front mount? engine temp could have something to do with it possibley as you might be getting fuel evaporation
