Put the 1.0 on, take it out and make a couple runs then swap for the other.. They aren't that hard to change.. Couple hours Max

Just finished up with my truck doing a couple of things. Got the 1.0 on and it seems a bit underpowered compared to my .90. EGT's are not nearly as bad, but it is smokier and I could tell a power decrease even on my smallest tune (1000us) which normally is still a decent tune. Waking up tomorrow to swap the .90 and wash it, throw in on a trailer and cross my fingers. Might dyno it depending on if I have time. Drive pressure with the 1.0 barely touched 60psi, which I'm thinking I need more drive at this elevation.

Swapped the .9 on this morning. Ended throwing it right on a trailer and taking it to the drags. When I got here after 3 test passes I decided it's too big and I couldn't stay on top of the charger. Between classes I swapped in the s476 and it's been running consistent 12.4's. Not where I want it to be but it is progress and I am happy to be able to actually race it lol.
