Did you ask Procharger to adjust the tune or did you upgrade the fuel system?
I asked them to look into it and adjust it and this was their response:"I see the issue, the high pressure fuel pump is dropping pressure in 5th. It looks like the pump needs to be upgraded"
I was droping pressure because my cats were getting scorched, and the ECM demanded more fuel to quench the cats thus pressure dropping at high speed, I removed the cats and got a custom tune and the issue was gone.

I recently installed an A&A Corvette V3 Si Supercharger on my 2014 A6 Z51 with a conservative tune is what I requested..........A&A Si V3, No Meth/Alky, Carb Compliant, 93 octane, standard 7.65" balancer and 4" pulley, Borla X-Pipe, no secondary cats, ported throttle body are the only mods. As I look at my Dyno, my smoothing is at 5 and you’re at 0, I think the smoothing is the amount of detailed shows as in jaggedness but I am no performance expert and don't know what that really means but just pointing it out. Attached is my recent Dyno.....

I read up on dyno smoothness yesterday and you are right from what I understand. When we were running the dyno, acceleration was smooth all the way to redline, so I’m not 100% sure. I’m going to order TPS headers with X-pipe and get a custom remote tune most likely from PatG Tuning. Was the ported throttle body worth the $$ with your supercharger?
I had the throttle body on before the SC and I could feel the difference but I bought it used for 1/2 of the $500 price so for $250 I was pleased. The Solar Throttle seems to be the leading brand and I have read nothing but positive reviews on it.
I wonder since I am tuned would I need to re-tune by switching the throttle but then again, I will keep the TB that I have as 500hp+ is more than enough performance for street use for me.

To stop the flywheel from spinning without a flexplate(flywheel) lock which requires the bell housing off or the engine out, simply put it in 1st gear, engage the e-brake, rear wheels on the ground (if possible) and use a good quality torque wrench.
Remember on the Procharger order form you pick Stock or list your mods. This is why I didnt want to mess with hi-flow cats or TB.. not sure how the canned tune would react. One of these days though I might take a ride down there for the hell of it and tell them they owe me 20 hp. lol
