are they any good and wat benifits u get out of one

i have a s2 with a big valved head 285 t2 cam chipped stage 1 turbo

will i see any benifits wit hall that fitted

 

If your KE is working ok and you have a good cooler fitted that works well then yes an MF2 with an 803 5th and 3bar is a great upgrade allowing you to run up to 25psi IF the turbo is ok!!!

(Notice all the IF's as Im affraid RS turbos are a bit shonky these days!!)

 

its got a pace intercooler fitted

i wasthimkin of getting ome stu

 

Mmmm been thinking of getting a 5th injector for mine too

 

Personally I'd be going for better intercooler, bigger turbo and better camshaft before the 5th injector

 

i have a polished cross over pipe with a fith injector fitted and a boost adjuster to triger it brand new cost over £190 + vat iam selling £110 new with injector fitted

 

if u need more fuel, then its awesome way to do it.

I recently returned 45mpg on a couple of runs, as i can cruise at 15:1

 

ive had the fuel pressure mod to my metering unit, checked on lambda on road at 20 psi, and its fine.

 

instead of wiring up 5th injector, i got a boost switch wired it to my cold start injector, am able to run 21psi boost no probs, just a cheap way of doing it,

 

is this a good way to do it! am gonna do it myself or do i go mf2?
