Need help Procharger guys come on in.

[BMWM3]

Ok my tuner tuned my car with a good safe tune making low boost and I made around 530/475. The care runs perfect when he dogs it out, but the problem he is having when idle'ing the car wideband gauge will stutter and jump from 14 to 17 and back and forth, also when idling it will show it going lean and then going rich back and forth in the logs... he thinks their is vacume leak but can't find it as of yet.... He thinks he is going to have to run a fogger in the intake to find the leak.... Any body have ideas of where I can point him to..... In the tune Log he showed me only at idle there is a problem on 1st table of log... Any guys experience any problem with idle with prochargers p1sc.

2nd issue is that the procharger tube in pictures below he said he doesn't remember seeing one like this with the way the tubing is made has anyway else seen one like this.. He stated the ones he seen have no internals like this one to direct air flow.

My mods are
BRENSPEED 5.0 STROKER
D.S.S PORTED HEADS UPGRADED SPRINGS STOCK CAMS
PROCHARGER P1SC 12LBS
FORD RACING INTAKE MANIFOLD
EVERYTHING ELSE STOCK INCLUDING SUSPENSION

Can't see the pics to well but they will put something like that in the tube to clean up the air flow so the maf gets a better read

That's the older style of maf location. Procharger has since moved it to the intercooler. Your wideband bouncing could be from the maf location. Are the short term fuel trims bouncing too? How is the pcv set up? I had a hell of a time with breathers on my procharger. I finally had to go with a breather on the passenger side and the drivers side connected to the intake with an extra pcv valve.

Has your tuner increased the manifold volume to account for the extra volume in the frpp intake? IIRC it's a little over 12 liters which is about a third more than the stock one.

I'll get the data log from him and post it.... do you think i should update to a newer pipeing.

It always bothers me when I see threads like this. I really feel like the tuner should be able to say for sure, "hey, you have a "hardware" issue" or adjust it out in the tune otherwise. I'm not being a smarts, but what are you paying him for? I don't pretend to know how to tune, but I can def look at a scan tool and know what needs to be addressed, I would think a tuner should be able to smoke a guy like me, considering he knows the data/info so well he's being trusted not to blow up you car.

I trust my tuner he has worked on all my mustangs but I believe sometimes the best of us run into problems that sometimes have us stomped for the moment , I feel he is doing a great job especially when he is going out of his to way to make sure the tune is 1000% perfect he always put my cars together and he has done over 100 members of my club"s cars over the years and none have had issues with him working on the cars other than PRICE they charge sometimes, plus I love DYNOSPEEDs customer service or at least the way they treat me..... But your comment is true and does make sense no doubt.... I just feel that dynospeed is tackling my issue with all the knowledge and resources they have available and any insight I can shoot his way will help him

I don't think that too many tuners are going to know everything about every combination. That doesn't mean they aren't good tuners, it just means they haven't come across the issue before. There are a lot of performance parts out there, the combinations are endless.
