The dyno you are using IMHO is perfectly calibrated.
Is it a Mustang?

Can you run Stage 2 on 91 octane with only:

Dual cone intakes, Upgraded IC, 2ndary Cat Delete but with stock downpipes???

If so and it makes over 385whp and come with map switch, I'm totally there!!!

Based on the logs I received, a full bolt on car (top quality components) with the same tune is in no way producing more than 310-320whp (13.3psi peak).
But 360 RWHP for Map 4/5 on JB3 with all bolt-ons seems pretty spot on

I have been told you need to replace your stock cats (dp and secondary) with at least high flow cats if not completely catless. You will also need FMIC and exhaust

I don't have any logs on jb3 so I can not say anything about it.

Btw the Giac stageI is for sure in the 320 (real) whp range on a fully modded car.

I think with FMIC and catless DP's you can run stage 2. Might* need a DCI or atleast a new drop-in filter but not sure. Pretty sure EAS and Mr5 both have 2nd cats still (maybe higher flow ones tho).

I like this tune. I remember reading the original stage1 reviews... it does eliminate the lag between shifts right? Especially that DREADED 3-4 shift?

I was set to get the stage 2 beta file until I told them I still have stock secondary cats, you need high flow cats all around at the bare minimum

WOW, so Mr5 made ~70hp and 50tq more than you on a stage 2 with intake and catless DP's as basically the only difference?

Still quite high reading for my taste, but for sure yours are way more realistic numbers (in the upper range of measurement error at least)

here is a scan of my stage 1 dyno with fmic, catted dp and catback exhaust with stock secondary cats.

remember, stage 1 is not designed for a car with my mods, i need to get a resonated midpipe and then upgrade to stage 2

I wouldn't doubt that catless dp, dp-back exhaust, and dci would have netted u another 25 rwhp.
