I am running the 7 psi pulley on the comptech origianl setup. It runs fine and pulls harder from midrange all the way up. I have a emanage unit, but just ahvent installed it yet. I also have all the harnesses and software. I am going to get injectors, but Im not sure how big yet. I am going to swap to a 9 psi pulley and AEM eventually.

My question was once I get the emanage installed on this current setup, do I have to put in any settings or can I drive it without tuning at all. I have a 2 hour drive to get to a dyno.

Also lets just say that I loosened the BOV spring tension. Should I tighten it or is it alright a little loose.

I wouldn't be running the engine over 7k rpm untill you get an A/F chart on a chassis dyno.

When I installed my e-manage, I used the boost cut funtion to replace the vortech supplied MAP clamp, and no other settings. I then drove 3 hours to the dyno and swapped injectors on the dyno, before getting started with tuning. I also removed the vacuum hose from the FMU and reset base fuel pressure to 55psi with 440cc injectors.

I wouldn't worry with the BOV spring tension, you can control boost with your right foot.

I did similar, but swapped injectors at home and put a small injecotr compensation factor in the E-manage. I then drove half an hour to the dyno running rich as heck.

Also, you can always control boost by removing the belt and driving NA.

On topic, just take the BOV and your car in to a machine shop. You can probably drive away in a few hours... the adapter flanges aren't a big deal to make for any skilled machine shop

A little off topic : but someone mentioned that you can remove the vacuum line to the FMU on the Comptech Kit. Would that effectively have you running stock Fuel pressure? I have 500cc injectors that I have not installed yet because I thought I needed to buy a aftermarket FPR. If I can effectively achieve the same result by removing the vacuum line than that would be great.

Thanks,

I'm not sure on the Comptech because the stock regulator is removed and replaced with the FMU. You would be running a fixed fuel pressure, not boost or vacuum dependant like the stock unit or FMU. Usually the FMU will increase static pressure over the stock settings because it is a restriction in the return line.

The only way to check it is to put a fuel pressure gauge on and have a look what the pressure is.

I know Aus was using a SARD FMU instead of the Comptech unit with his e-manage/440cc combo.
