Correct. My 5th gen runs a steady 11.3-6.

I couldn't tell you TBH why it is at 12.03 but I'm not too worried about it. Like I said Nenni is coming down and I'm sure we will get a lot more power out of the car.

Justin Nenni from Boost Logic is coming down at end of month and I'm gonna get a tune session in with him. Should see the car run much better... especially street tuning it in this humidity/climate.

He is still stock. You have mods he dont. So yes he is stock. Hell he isnt even full potential stock. So you still have upper hand. You also have more cubic inches.

So yes even though he has a better bliwer and more boost stock he is stock. Your not. And why you are running weaked tuned you said he is also for 87 octane. Costing him who knows how much power. Also who tuned for him if detuned?

70-170 both starting in 3rd a GT500 put a half car on a Z.

This, and the 13 gt500 driver is well known on svt for having the driver mod and being a stand-up guy. Guy said both guys could drive and I believe him

Probably grease coming off the muffler bearings. Might have to re-pack em

+1 Agreed..
Had the same problem. I just used a simple finnigan wrench to tighten down the muffler bearings and all was fine after that.

GT500's definitely stepped up, awaiting GM's response

I'm guessing you don't tune your own car.

Sure am! But only spraying on race gas.

Remember I have meth.... I'm tuned on 87 oct/meth mix. If my meth gives out I go boom.

I have Alky Meth... I monitor that meth is spraying by monitoring my air intake temps... If they drop significantly at WOT it's cuz meth is working.. If they stay same go up meth pump is dead.

Yea, but if you are in the middle of a run you might not have time to look at everything. One of the most reliable systems is the Anderson Mr. Freeze kit. It has no pump or wiring to go bad.

True but you can noticeably feel the car when meth isn't on. It backfires and misfires like crazy.. Meth is tuned for power so its like injector #9... Very noticeable if it stops injecting.
