Good numbers for tune?
Good numbers for tune?
Hi I just got my car tuned and am wondering if 327hp/312lbft is a good number on 20lb of boost at 4300ft above sea level. I wanted a conservative tune, but am not sure if these are good numbers for the tune I got.
Mods:
Amsoil cone filter
Walbro 255 fuel pump
Halman MBC
Perrin downpipe

Yah i get that but usually you will see a spike, depending on boost control method. So like 24 tapering down to 20. Your numbers seem right based on your mods. On that note though peak numbers are a poor indicator of performance. How does the car feel? Does it pull hard all the way through the powerband? Do you have a dyno sheet you can post so we can see area under the curve?

It does pull hard through the powerband and I like the fact it is running about stock boost. So it is hitting 20lb peak boost then tapering down to about 16 or 17.

You asked for a conservative tune and that looks conservative to me 20 tapering to 17
/\ as slowsrt4 said why not more boost as you are at 4000 + ft altitude ? At the least you can hold 20 psi all the way to 7500. Switch to 3 port EBC and you will get better control of the boost curve and take advantage of the ECU's ability to control boost for weather conditions and temperature.

Thanks everyone for the responses!! I just wasn't too sure if I should be getting those numbers based on my setup.
My tuner did mention to me that if I wanted more power, I had the mods capable to make more power by having it tuned for more boost. As tempting as that sounds I was content with the conservative tune. So there really isn't a reason as to why I didn't run more boost. I was just content with the amount of power the car is putting out.

I'm still learning how to tune and I want to study all I can.
