Need some HELP with Vortech

Need some HELP with Vortech
Well here is a copy of my dyno sheet. It starts to lean out pretty bad around 3300 rpm and it just gets worse and worse. I am using all of the stock vortech components (fmu,emu,inline pump,and SS box). My mods are exhaust, test pipes, and plenum spacer. Should it be leaning out this bad with just these mods? Also it seems i have a boost leak somewhere because its barely getting over 5 psi of boost. And i know it sounds weird but i have the a 3.25 pulley on there. I know its an oddball pulley size but it was included with the used kit i bought. I was thinking maybe a combination of the pulley size and breather mods is causing the leaning. So any feedback would be appreciated. Also does anyone have the R4 tuning software for the SS box they could send me?

The FMU/SS box nonsense is your main issue. I dunno how many cars we've moved over to a proper setup and solved all the safety/driveability issue.
Atleast you were smart enough to toss it on a dyno and check to see if it was running safe.
This isn't just a Vortech issue, we see it in most basic bolt on kits. I'd contact Vortech first and see if they can get you dialed in to atleast a safe AFR. Also you might want to think about getting the standard pulley from them.

Looks to me like it's getting richer @ ~3K (not leaner) and then leaning out up until redline. The 3.12 pulley is supposed to make about 10PSI but I've read where that's dependant on the mods since restriction correlates into boost readings (e.g. free flowing exhaust lessens restriction and therefore less boost is created).
I am not a tuner though, merely regurgitating what I've been told.

You bought a used kit and probably have no idea what the SS Box has been tuned to.. You definitely need to get to a tuner that is familiar with the R4 S/W and get it tuned before damage..Exhaust mod's should not make it that lean..They are not unusual for most Vortech owners..

You could drive over and bring us the car if you would like and we could fully tune it for you. It sounds like you might have another issue going on as well if it is leaning out.

Sell that SSbox and inline fuel pump. Get some 440cc or bigger injectors(depends on your power goals), walbro 255 in the tank. And buy a utec. More power and way more safety. Supercharger's require way more fuel then turbo's. Water/Meth might be a good Idea too. Oh yea make sure your belts are tight........

+1 on the get a tune sentiment. I also completely agree that you should get rid of the SS box and go with better EM and fuel upgrades.
Good luck!

you guys are making it hard!!!! haha.
im not looking for big power or anything. Just a good conservative tune that i can enjoy as a DD. The shop i deal with a few really experienced tuners. I trust there work. Not to say though that i wouldnt love to take it over to AAM, its just to far of a drive from here
Thanks for all of the help so far everyone

IF you have some cash, go with what people are saying.. 440cc injectors, UTEC, and walbro and bring it to a good tuner.
If you dont want to spend money on those I would seriously AT THE MINIMUM consider taking it to Jeremy he is very knowledgeable about vortechs and could tune your car safely.

Did you do the boost pressure test after you got everything installed like I told you to? haha Look up my "Homemade boost test kit" and do that first. You could also have belt slip going on. I know it seems like a pain and more $ but since you are having issues it would be wise to just go with a Utec, DW 600s and a Walboro 255 and have it tuned at Injected since they are pretty close to you. Might take another week to get things together but not blowing your motor is always a good thing. I would just order a 3.12 from Vortech while you are at it. You might even be able to find one used along with the Utec. I would buy the injectors and fuel pump new. Good Luck!
