Since you've got the A-trim, use it to set up and get running. If it only makes 6PSI, that will be a huge horsepower increase. I know a guy who is a TBI-blow-through-guru. Send me your e-mail off list and I'll ask him to contact you.

big_g is the exception.

Had it pullied up for 16 lbs. of boost @ 6,500. Never a problem. No timing retard. No detonation. Blow-thru carb. set-ups (inter-cooled) are more forgiving on boost v. timing, imo
No one else I know has been able to run 16PSI of boost through a regular NA ignition timing. Usually that boost level would require half the ignition advance of the NA, say 18 or 20 degrees versus 36 NA. This month's Car Craft had a supercharged draw-through article and they said the max on 91-octane was 19 degrees. Yes, a blow-through with an intercooler will have a cooler charge, but are you really running 36-38 degrees of ignition advance with 16PSI?

thnx, jack vines
