So ever since I had the drop in fuel pressure which I have not mechanically tested yet my fuel economy has steadily went down since then. Have not had the chance to hand calculate yet but lie o meter says it went from 16.8 to 14.3. I picked up a tester today so I’ll be able to rest idle pressure soon. Where do I hook up the tester? 

 

The pressure went went down and then back up to 17 18 at idle and 12 13 wot. 

 

Used to be 19 20 at idle and 15 16 wot before the drop. 

 

I’m  thinking about going with 75hp sac injectors and hooking up the wiretap instead of 150hp sac and nonwiretap. If you guys are like me and you know there is more power there to use and you end up breaking things? I’m afraid that’s what is going to happen because with 150s and the wiretap available for use I should be able to put out 550 hp which I do NOT have the supporting mods for. With wiretap and 75s I can only put out maybe 450 which is my end goal for hp and which is already gonna be to much for my mods... what do you guys think? Big or small injectors? Wiretap or no wiretap? 

I vote 75s, that way you can drive with your tuner off if you want and not black out the roadway.

Wouldn’t 150s with nontuner also screw fuel economy? I’m sure 75s would prob boost it.

Will a Fass DDRP with relocation and big line kits fully support 450hp? I’m tryin to find the cheapest most reliable way I can replace my current airtex and not have to worry.
