The fins will get blocked by debris. Externally.. not internally.

FIC did that. Among others.. It comes after they refit/redrill/reoriface whatever to a stock injector.

But both of us have asked you to verify fuel pressure under heavy load and I haven't seen a...

After the changes I recommenced you would need to go back over the tune.

Again I'd be wary of any map sensor that wasn't an OEM GM part.

I'd encourage you to look into EFIconnection.com This is a complicated wheel to re-invent and he's already done most of the hard part.

It's been a long time since I've seen one.. but a injector that drips will cause a hard start.

I don't know where we are at.. have you mechanically verified fuel pressure while trying to crank.

thank you..

For me I used to be pretty guarded on what I know. I mean almost all of it came at the expense of fighting some problem here at the shop.

But I am/was involved in another...

Get a log with all the things we asked for earlier.

It could be that you are fast enough for 6th gear but not 6th gear locked up. The difference between the two might have you thinking its slipping.

When I do a A6+ with a loose converter I...

Any axis that has that little underline is editable

IMHO yes.. cost/hp for a good tune even on a bone stock car is on par or better than the return you get for headers.

They are doing this just to get the shift feel they want. IMHO they do a bad job of it... well better now days but when 6l80's first came out the programming was terrible and none of the shifts...

yes but also..the brake signal needs to be hooked up in swaps. Without it TCC lockup will be screwy... like unlock until 5 % or more.

the brake signal is opposite to what you would think. It...

you likely have something else going on. Has the condenser been blocked by dirt/sand? common from where I'm from.

This ridge in your VVE table looks boundary zone induced... meaning when HPTuners calculates the VVE table it can't get it to fit properly in the zones setup in the tune. I can do the math on better...

Sometimes more power is found richer.. You don't know until you dyno it.

I will tell you the window for making good power AFR wise is fairly wide. If your in the ball park and not so lean you...

Yeah the tune really doesn't look great. There won't be one or two things that fixes this.. I'd start completely over to be honest.

Take the idle timing down to 18 degrees or so. You want some...

Is there an obvious difference in how the car is running on this lean restart?

While the engine is hot in how we think a engine is hot.. it isn't like running hot on those restarts. Only the fuel...

The MAF is enabled on this. For that reason what you doing to the VE table really isn't having a direct effect on fueling. You would need to disable the MAF to tune the VE

that doesn't look great to be honest. I'd continue to watch it... especially under a heavier load.

It sounds like you got a miss other than that.. have you done the simple things? Wires/...

Change the map sensor values to 312.5 -11.25

add short term and long term idle trims also LTIT STIT get plenty of log with it completely stopped.

Something is wrong with the map sensor. It's reading about a 1/4 of what it should. The tune file is setup for a stock map sensor. Is that what you have?

It should read near 100kpa with the...

They work. but an old style that is not as clean as a lot of other options.

I'd be wary of aftermarket map sensors. There is a turbo company that sells one. I've had several come by the shop and all of them were bad.
