hi folkes, well im begining to pull my hair out now. my problem is some times when i boot it it does not pull like i should, feals flat and other times it goes like stink. ive done a ecu check and no errors and ive checked my o2's and they are fine. i just cant put my finger on whats wrong with it. its got to be something electrical.. ive got a greddy profec b controller and on hi it holds 15psi. (ive put a stage 3 jwt map at the mo i dont think its this though)

 

all the things ive swapped are as follows..

 

tps

water temp sens

fule temp sens

knock sens resistor mod

o2's

 

the only other thing i can think of is tryin track down some one that has conzult near me (stoke-on-trent).

 

help guys :bow:

Boost leak, despite seeing 15psi the leak could be been made up by ever hard working turbo`s, a leak will always reduce spool up time and give more lethargic performance.

for got 2 mention i tested the MAF and the reading was 0.4v in the book it states it should be 0.8v could this have anything to do with the flatness all the time.
