Ok so this might be a stupid question to some but I am going to ask it.

My car is currently tuned with a 3" turbo back, test pipe, and a drop in K&N filter. I am going to order a Greddy profec B boost controller and an upgraded fuel pump. after I install those do I need to get my car retuned?


Thanks

 

if u raise the boost u need a tune... or jus leave the boost where it is now and u wont need a tune, even with the walbro

 

don't bother install the fuel pump until you plan on getting a tune...the car will run rich and your gas mileage will be poor

you can install the boost controller just don't alter the boost level above what the car is currently tuned for

 

if i were you would not order the profec, thing is such a nightmare to you use...or atleast for me it was. just get an MBC, evos do great with mbc and they are cheaper than ebc's

and like everyone said, if you get the walbro get tuned for it, your gas economy will suck more than normal and youl run rich

 

I agree, get a mbc a pump, and then raise the boost a little when you get it tuned. You should be happy with the new power.

 

as everyone else has said.. if you are getting those 2 items dont install or plan on using them until you get a tune!

 

odd response, I love the profect b spec II and so do my customers.

good advice

 

Tune.

 

its a love hate thing, some love it, some hate it. as for me, im an idiot i like the simplicity of the MBC's

 

nothing wrong with that...I prefer to keep things as simple as possible for my own car as well but I run pump and race gas and the Profec B spec II keeps two separate boost profiles handy. Also wheelspin is a major problem on the street so I launch at wastegate boost, press a button on the greddy remote switch and let it have full boost when I get into 2nd gear

 

nice james bond mode!

 

I also had a nightmare experience with the profec.

 

yep, missiles shoot out at my competition if I spin too much..hell of an EBC I tell ya

 

great that helps a lot thanks guys. I think I will start with a MBC and then install the new fuel pump when I am ready to get it tuned.

 

What MBC do you guys think is the best?
