boost or timing for hp

[95tsi]

Just a basic question as to which is going to have better results for HP. I am tuning with dsmlink and just playing around with some settings to see what happens. On my "street" tune I run about 16-17psi(13.0@100) on 92 oct. and pull around 12 degrees of timing at 6000rpm.

Trying to figure out if I would make more power dropping the boost and upping the timing. For instance 14-15psi and 17-18 degrees of timing? Or, am I good with what I have for no dyno time?

Boost will typically yield more power than timing. I would keep it where you have it assuming knock is nonexsistent.

Seems to me the timing is very low for 6k rpms if you have a 2g like your name states... Your probably getting a good bit of knock to make it that low. From everything I have learned it should be around 17-19* around redline and while logging it should be nice and smooth from around 10-12* at about 3k rpm all the way up to 17-19 at redline in 3rd gear. Any dips in timing usually results in the ECU pulling timing because of knock.

I am truly not positive if that is correct but this is how I have learned and I am here to learn more also so if I am wrong please correct me.

This is a tech thread, give us a mods list. Generally boost is better, it depends on the turbo though. With a dinky turbo the air might be too hot and you would be better off with timing.

from what dsmlink is saying there is no knock.

as for mods, yes it is a small turbo FP T-28 but that shouldn't be just making heat at that low of a boost setting. As for mods, 550's, fmic, 3" exh, dsmlink, air intake... just the basics. Only way I could get it to not knock was by retarding the timing on dsmlink. With 110 octane, I will run around 17-19 degrees at 21psi.

Hope that might help give you an idea. And maybe some suggestions.

Boost makes crap loads more power than timing. DSMs aren't the most timing sensitive cars either. They don't have big power gains when you add 2 degrees like some cars. Shoot for something like 15-16 degrees and as much boost as it will take on pump gas. 2Gs don't need as much timing as 1Gs, due to the higher compression. You could run more timing, but I would just go for higher boost.
