hack vs. advancing timing?
ok, i heard that if you use the hack to control your 450's and boost that it advances the timing. this isn't good on a boosted engine. what would i do to get around this? could i just use the hack and get the msd btm and retart it like 1 degree each pound of boost?
not running boost yet but will be soon. i'm planning 7-8 on the street and 10-12 on the track. most likely only 10 tho, i have to much sweat and money in this engine to blow it being stupid.
You can also chip your ecu for retard. I guess that works better at lower psi and it would be cheaper than a msd btm too. Then again if your doing that you might as well chip your ecu for boost while your at it.
lol good idea but i don't know how to work all that pgmfi.org and gettodyne and turboedit ---- anyways. i've tried to comprehend it before and it just doesn't work. does anyone sell chips that are specifically for boost and retarding timing?

The BTM would work great or you could just back your timing down and how much boost are you running?
