Short answer, yes. He didn't feel confident in getting the scaling done and decided to stick with the OEM MAF setting I had. I peg the voltage at around 4600rpm when in boost. Not really happy about it but it is what it is. Perhaps it's because I'm using a larger Mag tube than oem, why it's soo hard to scale the MAF accurately.

Time for a new tuner; I've used a PMAS and a larger diameter tube for the longest time, and while it wasn't easy on my tuner, it can be done...

The Larger MAF Tube will benifit the MAF, not hinder you.

Yea, well I'm heading straight to the shop after I finish work. I'll keep you all posted on what's going on. And I appreciate everyone's help. Hoping the scale 2bad240 will send me will help with my pmas.

Soo today has been a very big frustrating ordeal. (*Inhale, exhale) Ok, this is what's going on with the car. The Z was fine before leaving it with Hi Psi, The shop has had this car for 3 days and only done 3 pulls on the dyno.
FUEL: I am at 93% duty cycle at redline with the Meth injection at full boost with 11.5afr thruout the rev range. The tuner (Justin Nash) refused to tune the car aggressively with the injectors operating at the ragged edge. Bigger injectors and a fuel return system would need to be purchased to continue.
BLOWER: The V3 seals are somehow shot now, the self contained oil is now leaking from behind the impeller, which it didn't do before I went to the shop. So a rebuild is now in order.
ENGINE: When I started the car on the dyno to back it up, the exhaust was smoking pretty bad, mostly white, blueish smoke. It continued to smoke idling. The car also sounds like it's missing/misfiring. I was not happy about this and addressed why the hell the car was doing this. Tuner said it smoked during the dyno runs (which Is why I am wonder why the f*** he continued to run the car hard and not call me about it). I checked the dipstick and noticed it was milky (Clear sign that the coolant is contaminating the motor oil) which I had no issues with during break in. Car was completely normal as I regularly check fluids on my own until they touched it.
MAF: I received 2bad240s MAF table for my PMAS but couldn't continue with tune due to the issues I am having with this shop and my damn car.
So right now, the car has been left with them. I am royally pissed off right now. Car was perfect before any of this s*** happened. How in three days my car ends up like this is complete bs. After a long discussion on what will happen next, they will be charging no labor costs and will be performing a compression test on the car, as well as replace my head gaskets if needed, but I need to pay outta pocket for new gaskets. The blower will have to be repaired as well. Truly a sad day for this Z enthusiast.

Sorry to hear man, damn. I do know of builds that did well during the break in period but when driven hard on the dyno had issues similar to yours. Did you go with the L19 head studs or just the standard ARP? Also, did the same place that did the build do the tuning? I hate being in the predicament where each place begins to point fingers at each other. Maybe you should give Vortech a shot for the SC rebuild. I think you tried two different places and didn't have much luck. Why not go with the place that manufactures it?

Shitty shitty situation. Who built the motor? I would not let them touch the car PERIOD. After this. Have them do the compression test. If they built motor. Attempt a refund or financial agreement and part ways. As a tuner I would not let them touch it again. And if it's a different shop who built the motor. I would take it up w them and not let them build it again. Best of luck man. Hopefully you get this worked out

Thx I appreciate that. And I agree. I've done the majority of mods on this car and I put alot of work in my build. It just sucks when you put your trust in a shop and give your prized possession to them to build and modify and they ruin it. This is the same shop that installed my shortblock mind you.

either way.......
"DO YOURSELF A FAVOR"
Upgrade your fuel system with at lease a CJM Stage 2. ( Talk to Colombo to see what pump he has) The problem you have is not your injector size with your existing setup, but stock fuel line size, it's very tiny. The CJM stock fuel line replacement is 1/2" diameter. and you may need larger injectors to match the pump and blower.
The New Vortech V2 Ti-Trim HD Blower is your best choice.
And YES YES get the L19 Head Studs....

I was referred to Built Industries in Florida for the shortblock assembly. I don't think the block is the issue As it was fine even when I went full throttle on my own self tune to redline. It didn't show any of the symptoms it does now that the shop tuner touched it. Yes it will be worked out, Justin promised to not charge me labor but I would need to replace the head gaskets out of my own pocket. After they fix that I'm taking the Z back, repairing the blower and revamping my fuel system for more power potential.
