Went to the Dyno today
Well went and got my car dyno'd today to get some baseline numbers before I started more heavily modding such as pulleys and injectors. I did two pulls and my best of the day was 218 hp and 197 tq. My mods are in my sig. I was happy with it.

i'm going to go with 60lb injectors and a 2.7 pulley. I don't know whether to go heat exchanger or dual pass. Then i'll have the same shop dyno tune it.

You doing a third gear pull is the reason your numbers are so high. I did a 4th gear pull because it is closer to 1:1. Everyone i've seen doing a third and fourth gear pull the third gear pull is always way higher

not for sure you will see a big increase, but when you have it dyno tuned it will give them more room to play with and keep you IAT temps down

I think I am also going to run meth injection

Third=263/231 fourth=247/228. Big difference. Difference in third from 1:1 is .18 over and fourth is .11 under. So we will never get a true reading. It will either be high or low I guess.
