Okay so first off mod list:
K&N hot air intake, TOG xtreme ceramic coated headers, XP cam, 42.5# injectors, 105# crow springs, LS7 Lifters, borla exhaust, "X" supercharger pulley, GenV M90 Supercharger, Racing Transmission, SS intercooler with ZZP Stage 2 heat exchanger, 6.95 Pushrods, ZZP Poly Motor Mounts, Northstar Throttle Body, Valve Cover Breather, ZZP Plug Wires, Autolite 103 plugs
This car was dyno tuned by ZZP but it was dyno tuned when I was running too long of pushrods so its probably off a bit now that ive switched to 6.95s. Basically with a 3.25" supercharger pulley im getting roughtly 9 pounds of boost spiking to 10 for a split second. With a 3.1" pulley im getting like perfect boost. 9.5/10 spiking as high as 12ish. However, towards the shift point of 3rd gear it ends up hitting up to 4.5 degrees of KR. It had 0 KR with the 3.25" Pulley. As far as I know timing has been set to 18 but the highest ive seen is 17 on the aeroforce.
I guess my question is do I put the 3.25" back on and just say F it knowing Im not at max power. Or do I keep the 3.1 on and send it back to ZZP for another tune. I dont really like the idea of losing anymore timing but it is a lot more closer to optimal boost. Can they add more fuel to fix the KR? If they do is that going mean less power than lowering timing or running a 3.25"? Dunno what to do really. And please dont simply tell me not to have ZZP tune it... really just want to know if its better to have less boost with my current AFR and timing or more boost but doing something to AFR or timing to get rid of the KR..
