SC Install resulted in 50 more HP...suggestions needed

@bcfromfl...yes i read that thread and look like a future addition, but I want to make sure the curren t set up is working as expected before i add more unknowns to the equation.

@MoulaZ...I paid for the canned tune, but accordin to the dyno I have 50 out of the 110 to 120 HP they say i should get with the canned tune.

@ChaseZ...not sure the type of dyno, i could fi nd out but i dyno'd the car just before install on same dyno and same guy and it showed 290whp which is right in line with Nismo numbers. It is way too low, I agree something is up. Just not sure how to tell if it was bad dyno, install issue, or tune issue.

@king...honestly, i was expecting to feel more, especially given a smaller car compared to a stang...but i know larger displacment engines produce different effects...i just never had the opportunity to witness the two differences given equivalent hp numbers.

Heck I'm not saying the tune isnt right or the install has problems because i did see the boost gauge hit 7.6 on the road...but the dyno pulls didnt give expected results nn d dont know why. I could oo another dyno run somewhere else for another $180 or a smoke test for ?. I looked through data and i can tell when i go wot...i can see my afr values at 10 the whole time from 2500 to 7000 rpm...among other data items, but i dont know if those numbers are appropriate and what else I can determine from all the logged data. Was hoping to come to conclusion of do another dyno or do smoke test based on numbers. What can I check?

Anyway, thanks for you concern and comments.
