last time i left a thread my car was as slow as ever 16 @ 88mph in the 1/4.

---91 GT with headers,xpipe,dynomax bullets,moroso cold air, cobra intake---
used to be running 14.8 with xpipe and bullets alone
so the answers i got were a vacuum leak or timing
well it was both
it has a header leak and the timing was off
timing was set with spout on, OOOOPS
man i can feel a real difference with the cobra intake
sorry guys no timeslips yet
next time i update with the timeslips
thanks to all the guys that gave info

Never seen a header leak cause that much of a loss in power. But if your timign was THAT off, then I'd say it might be that slow...

I recall reading that a bad enough exhaust leak right at the header flange can cost as much as 40 HP. I cant name the source, though.
