i have a h reg fiesta turbo on ofab it went on the rollers the other day it made 120bhp at 12 psi with the chip and with out the chip it runs anti lag and wont rev past 4 grand i have tryed another ecu loom map sensor standard injectors checked the fuel pump checked the cam and put the standard one in still the same checked the compression changed the spark plugs i dont no off any thing else it could be any help would be nice

 

your post doesn't make sense runs antilag when the chip is removed??? thats odd

and if it only made 120 with a chip and 12psi you have serious problems!!!

 

something seriously wrong here by the sound of your spec you have stage one ofab conversion so where does anti lag come into that spec normally, you must mean something else..... it sounds to me that you have serious bottom end problems of some discription, a decent tuner will tell whats wrong.

 

there is nothing wrong with the bottom end done a compression test and that was fine.When u are on the spot with the chip out it will run 0.5 bar off boost, any idea's as i have no clue now and saying i have serious problems does not help me fix it. The car went to a tuners and they could not find the problem

 

how can the turbo run 0.5 bar on idle in not on boost!!?? we can help you mate but you need to start explaining better than that

 

take it to a decent tuner

 

Have you checked the plugs to see if you're getting a weak spark? If so then I'd look at swapping the coilpack over for one from a scrappy (any EDIS equipped CVH Ford will have one at the scrappy - they should cost £10 or less). Once changed and you find it's still giving a weak spark then I'd say check the CPS and after that look into something around the ECU/Chip/Fuel pump side of things.

Cheers,
