i know i need larger or more injectors, which is the best value for money with regards to injectors, bigger ones and dastek or 5the injector and mf2??
also i was wondering about compression, i was thinking of runnin a decompression plate, where is the best place to get one of these from?? also what sort of boost could i run with a decompression plate??
cheers in advance

you can get an mf2 unit & a sig/con which controls 1 or 2 injectors that are located in an elbow before the tb, these will spray fuel into the tb and give you the fueling you need for when the car is on boost. when its off boost you are just running the car as is ment to be. (using the mf2 and a sig/con you need a bigger map sensor and bigger fuel pressure regulator, gmc motor sport sell all of the bits you will need)
however, you will have more reliability and a better more efficient setup if you were to run a standalone ecu. kms or omex to name a few but there are a load that will be up to the job.
as for the de-comp plate, the idea is to increase the gap between the piston crow and the valves, which in turn lowers the compression.
a few head gaskets together will achieve this but it wont last long and can cause problems.
you can get a de-comp plate made up a place called ferriday (spelling lol) engineering do plates to order, you tell them your spec and they will make a plate to suit your needs.
but you will be alot better off fitting forged low comp pistons.
its all down to your budget
hope that helps?
by the way, running a decomp plate isnt the solution to any problem.
the main factor is ensuring that you have the correct fuel for the boost you are running.
this is the important bit
if you run a turbo setup with incorrect fueling and too much boost. it will fly for a few mins then just die.
if you dont know what you are working with and what you want to achieve and how. you really need to pay for someone to do it for you, thats why they are the specialists, they do it day in and day out.
