Intercooler or Fuel pump?

[sLo-32]

Heya

I need a power upgrade and just wondering whether to go for the cooler or the fuel pump?

i got the car tuned last week and the guys said the car was leaning out up top...

dont know whether to go the cooler or the fuel pump...

What are your suggestions?

cheers

Fuel pump will only make a difference if ure current 1 is rooted.

If its leaning out, u may want to look at an aftermarket cpu.

What other mods do you have?

What sort power is it outputting?

You may be best off looking for just a Fuel Pressure Regulator...

If u are already lean u wont want anymore mods until other issues are accounted for, ie in this case the fuel pump. If it is the fuel pump and not the ECU, then i would recommend getting that problem fixed then after that u can get ur I/C.

Btw its not like a fuel pump and an intercooler cost the same so why u comparing them?

Hi sLo-32, did the dyno guy check the fuel pressure? That would tell you whether the fuel pump is running out of flow. Which would mean fixing/upgrading the fuel pump is the way to go. If they didn't check it, well your guess is a good as mine.

Hope that is of some help.

if it is leaning out the fmic will only make it lean out more

sort the fuel problem first

I will go fuel pump and management system. FMIC can go last.

Thanks for the input guys. Current mods at the moment: 3 inch dump pipe from the turbo, 3.5 inch exhaust, air filter, bleed valve and running 20 deg advanced timing. nothing too flash

The guy tuned the car on 10 psi boost with that advanced timing and said that i shouldnt really run more boost with the timing that far advanced. The car only put out like 125rwkw but that doesnt phase me too much cause it seems alot quicker.

I think rev210's constant ranting about dyno readouts have rubbed off on me (no offence)

I have also discovered that i have an exhaust leak around the dump pipe Could this be effecting the afr?

Thanks again

if its leaning out with just those mods then your fuel pump might be stuffed, as they usually run very rich stock and u have to lean the a/f ratios with a piggy back or aftermarket comp to make more power and have better fuel economy.

Fuel pressure doesn't mean anything! You can have fuel pressure & no flow & you will have problems, cause this is what happened to me. I had 40 psi pressure & 1/2L min of flow!
