Let me guess, start off fine, goes lean, levels off then shoots off the scale?

Don't Sleep on My V6

This was my first TT run at 3psi's and a bad tune. So don't feel bad Baylor. My torque sucked so bad on this run. But this was the log that got Vince to tweak me to where I'm at now. This when I ran to 15-17 AFR's. Sent from my iPhone 4s using Tapatalk

**UPDATE**
Ok guys, here's where I'm at right now. After that dyno pull I called Vince and we talked for about 20 mins, the guy is extremely nice and I cannot stress enough how helpful he is. Anyways, he was saying that my 354 hp pull looked a lot better and has no idea why my afr looked like it was going all over the place. By this time the shop needed to get my car off the dybo because they were closing. So when I get off the phone with Vince, and pay for my dyno time, the guy goes "Oh so when we took OUR wide band (which is about a $6,000 wide band) off your car it looked like it was barley making connection, which would explain the erratic afr. The guy that was doing my dyno pull was watching my wide band and said things looked good. Anyways, My car in the end made about 360 hp and 305 tq to the wheels, and Vince said he wanted to make some tweaks to the tune because he can get more power, so I need to load that tune in now. I just won't be able to dyno it. However I would expect about 370 rwhp and 310 rwtq. Vince did mention that my MAF is at the max reading and he is trying to see if he can figure a way to increase it, but he's not sure. Hopefully the JET MAF is legit and not a pos mod, because it sounds like we might need it. Was this used in my car? Because Vince said this is another way to get around my issue with the MAF. It would just require another tune..

Update from me (Baylor, tell me to shove off if I'm intruding your thread too much). We got the HPFP on and it was running way too much pressure (2400 psi) at idle. We ended up just removing the codes and it no longer went into limp mode. Fuel trims are a bit off to the rich side, so it looks like it is pumping more fuel. We called it quits for today and will resume in the morning. Hopefully it won't be 100 degrees again.

Yeah I was talking to Vince on the phone and he said that he still hasn't figured all that out yet, lol.

I have a question as well. I'm not bashing either, promise. I'm looking to start my research on fi as I save up the money and decide on a system. At this point I want either tracy's supercharger or his twin system. The only thing I want to ask is why does the ipf super seem perfectly fine and the rx having a little bit of trouble. Could it be the tuning? Any ideas? I don't know nothing about FI so I'm looking to learn.

Hello !
IPF-Tuning spend countless hrs of Software design on the EVOMS Mustang Dyno and on the road with the 3.6 LLT and LFX Supercharger Camaro until the SC-Camaro was driving like a normal factory produced car , just with much more power . Our working experiance with Audi 4.2 V8 Twin Turbo and Supercharger and Lambo Gallardo 5.2V10 Supercharger ECU applications over the last years helped al LOT to create an outstanding Software for the Camaro LLT , that is using the SAME ECU BOSCH ME9 like the Audi and the Lambo ! The keypoints for the hardware design followed by the software application were : 1) AFM MAF located with much bigger Housing on the INTAKE side of the SC to prevent intercooler humanity , oil spray and signal max. out effects 2) charge air dump recirculated into the intake system after AFM MAF 3) intake must get cold air from fender housing not from engine bay greets ASH@IPF-TUNING |

This is where the MAF sensor problem Baylor and I are having is coming from. They aren't broken, cracked, faulty, we are just maxing them out. The ECU has a preset limit build in that Vince can't alter. Once we go beyond that amount of air flow it can no longer calculate an accurate air/fuel mixture.

Hello !
One of the BASIC ECU engine protection functions of the BOSCH ME9 ECU that is used in the Camaro LLT is to run the engine in safe mode when the AFM (MAF) is maxed out for longer then 0.1sec In the safe mode the ECU is pulling the ignition advance away and mostely closes the trottle body to a low value to protect the engine ! NOBODY should change that basic funcion because of wrong or inapplicable hardware design of the AFM system ! Only way from the engeneering side is to install a propper designed AFM (MAF) housing of 100mm (4") diameter , that the AFM (MAF) Sensor is NEVER maxed out even at lowest altitude and lowest ambient temperatures at full load with max boost in use with with low backpressure exhaust systems ! Hopefully could clear the situation friendly wise with true technical explanations ! Greets ASH@IPF-TUNING |

Well, a larger intake tube would be an easy task, I just want to see if this pump will keep up with the boost!

I kinda like seeing the issues and the solutions... as long as there are solutions. Its way better than things being hidden from potential future owners.
