Hello yall I will be installing a racetronix fuel pump next week, is there any tune adjusments needed for this upgrade?

Hey Chris,

As long as you're not changing fuel pressure, you won't need to make any adjustments.

good luck mang.after the install you might want to put a fp gauge inside the car to monitor fuel press.should be around 60-62 give or take.no need for tune adj.

When i installed mine it increased my fuel pressure to around 66psi at the rail, but like the other guys said you don't really need to chage anything. You could adjust your injector flow rates to reflect the new fuel rail pressure, but you don't have to.

Could get a adjustable regulator but I guess that defeats the point.

I had to slighly retune my car(lean it out). My FP went to 58 PSI to 64 PSI after my racetronics pump install. but after about 2K miles the FP slowly started to settle back down to 62 PSI and has stayed there.

After my Racetronix pump install, the rail pressure only increase slightly, from 58psi to 60psi.

I didnt bother updating the tune, seems to be running fine with only that minor change.

Where do you get this pump from and how much? Is it an easy install? Sorry for the hijack.

I bought mine from Thunder Racing, one of the Sponsers -->

I also bought and has the wiring harness installed,
I think it was about $250 for the whole kit.

Install? haha, either drop the tank or cut a 'trap door' into your rear hatch well area.

I decided NOT to cut up my car, and have the tank dropped.

If you drop the tank, its best to have it cleaned out also. Might as well do it right, for the new pump and all. just my 2cents.
