right im having a crisis im running a 2ltr zvh with efi head etc so running ofac fes turbo management was running 7psi on standard injectors fine but was told that i could run 14psi on standard injectors with a chip so on went the chip and a twist of the bleed valve but wen i accelerate its like im hitting a block come off the accelerator and straight back on and she hits 14psi fine so wot could be causing the block first of all??????????

anyone feel free to help plzzzzzzzzzzzzzzzzzzzzzzzzz!!!!!!!!!!!!!!!

 

who told u that, kwik fit ? your engines a 2.0zvh not 1600cvh which you MIGHT get away with running that on a T2 turbo.
you havent even mentioned what turbo your running!
sounds like the cars been bodged togther, should be mapped properly to get it to run safely.
grove garage or msd in blackpool can do that

 

As Gav says. I'm amased you haven't killed it. You can't just whack th eboost up an expect the engine to cope. Im at 15 psi on a CVH and that needed beige injectors on light blues it's liking a ticking bomb. Turn th eboost right back down before it ends in tears
