OK I'm back from LaSota Racing!
The good news is the car made 180.42whp and 176.37tq @5psi.
The bad news is it was at 5psi.
Also good news is I have no oil or coolant leaks!
I had 1 obvious vac leak but fixed that by plugging in a connection all the way.
I got that done before I drove to Columbus.
I seem to be having wastegate issues..
The boost is "fluttering" around 5psi.
I'm using the wastegate that came with this turbo.
(TBird guys read on)
If I try to manually pull on the wastegate actuator rod it pulls fairly easily..
If I pull on the rod of the older/rusty looking one it has significantly more resistance.
I assumed the freeer moving one was the better... was I right?
Is it possible the spring in this is bad and the exhaust is actually forcing the wastegate open??
Another issue I'm having is a backfire when I left off the gas from higher rpms in boost.
Don, my tuner didn't really seem to care about it, but it seems something isn't right there.
Maybe something with the boost fluctuating?
I have pics and video but need scott to download them off his cam for me.
Everybody gets to hear my annoying backfire.
My exhaust is also louder than I expected.
It's not too bad until the wastegate opens, then it drones like crazy around 3k rpm.
Fix the boost issue.
Don says my current tune should work fine when I get the boost issue fixed, but just in case to monitor it with a wideband before going too nuts.
Anybody have a wideband I can bum or purchase?
If I buy one does anybody have a recommendation?
Fix my exhaust.
The section of exhaust crossing over the rear crossmember is rattling and driving me nuts.
