Looking on RST Mania and found a link to do with fuelling mods with the pressure actuator on the side of the metering head. I am wanting to get this adjusted due to me pinking at 17PSi. Is this mod worth doing. I have been looking into making up a fith injector kit with an adjustable pressure activated switch which I've got off ebay. I wanted to wire it up so it turns on the cold start valve at a certain PSI. Has anyone done this mod? Obviously I'd need to get it set up properly on the rollers once its been done.

 

i had the fuel mod, it was good, i wouldnt bother with one of those pressure switches, take it to a decent tuner and get them to do it properly

 

ive had a pressure switch linked to cold start jector,
works fine av also got fuel mod too and am runnin 21 psi hold, peal @25

 

zvhrst, can you post all of the parts nesecary to do this, also some pictures would be cool.
