Catless. Charcoal filter delete. Thats all

[G-M5]

Thoughts on numbers?

[Jasoneo5]

Normal for 91oct, maybe a bit on the low side. Would expect more in the ballpark of 625-640 as I have with BM3 and identical mods

[nencmeister]

Seems a bit low?

On the stage 1, like in your sig?

I think (even for 91 oct) his figure seems pretty low

627whp (lowest) - 642whp (highest) I ran with DP's and BM3 on 91 octane. Don't have the sheet handy but it was 82 degrees that day

I'd be hesitant to run a typical octane booster, usually they leave an undesirable byproduct on the inside of your motor, but I can't speak specifically to the Lucas product. Red Line has a Complete Fuel System and Injector cleaner that also says reduces the need for higher octane by up to 2pts; I run about a 1/4 of a bottle at every fill.

Works just fine since my car was dyno tuned with it.

Thank you for sharing OP, do you have baseline numbers?

Does having higher octane boost power or does tune need to be changed?

Adding octane won’t do a lot without tuning for it

it may get you closer to your timing targets (more power) but to maximize higher octane you need to tune for it.

On stage 2 i would expect 640+ whp and torque depending on how aggressive of a map you requested. To have a "stage 2" and be under 600 wtq is a bit on the low side.
