Re: 1/8th mile shakedown
got it out.
IC is off, plenum came off, transfercase is out, crossmember off (of course), with the plenum off i figured i'd take the valve covers off and check the rockers. look good. almost took the DP off, but enough is enough.
your wrong Mike, i didnt need a step stool. i used this

Re: 1/8th mile shakedown
well, it now launches at 8psi, 3300 rpms. more RPMs if i hold longer, more PSI if i pump the gas. stock brakes still hold.
when i launch, alot of weight transfer, and it pulls the front end hard to the left. i can feel the front tire spinning, but i'm not sure about the back.
i still have more tuning to do. running it really rich to be safe.
but overall, the truck is good now. :tup:

If you want to know more history of that convertor let me know. I am not original owner but first one to use it, E got it from me. I recognized the dripped black paint on it. LOL
I never went fast with it, but good news is it never was hooked up to a trans that broke. When I sold it to E it was still very clean in terms of fluid that had gone through it.

Re: 1/8th mile shakedown
the converter shop said the lining was worn. so they relined it, new bearings and restalled it. $200.
i believe the converter was also holding my RPMs down on the top end, cause now the truck shifts at 5400, right where the trans is built to shift.

Re: 1/8th mile shakedown
the new stall pretty much inverted my VE graph. its now a huge valley, instead of the hill. i gotta take my 77x down abit to make the curve better.
my largest drop in VE was 15 points, average drop was 12 points, all in boost/powerband RPMs. First time i drove it after the converter, i hit 10afr at 5psi. lol it was WAY rich.

Re: 1/8th mile shakedown
You mean something like the stall of a convertor would change the tune. No wonder why a chip from 1 truck won't always run like it should in another. EUREKA.
