I just spoke with darth fiero(www.gmtuners.com) about getting a basic chip done.
I couldn't really find an affordable dyno around me so i just decided to get a basic chip burned with only a few changes.
I'm gonna do this:
Raise my warmed up idle to 1100 rpm
Raise my shift points to 6100 rpm
Raise my rev limiter to 6200 rpm
Advance my timing by 3 degrees
And removed speed limiter.

Nothing too crazy, just wanna raise my shifts a little and advance the timing a bit.

Probably gonna catch some heat for not getting a dyno done but i think i kept it pretty basic.

Watchya think?

Sounds ok, but the idle seems a bit high? Maybe 1000?
Can they increase the tranny line preasure too?

Why raise the idle rpm anyway?

I checked out GM tuners also. If I knew EXACTLY what I wanted it would work great.
If I knew exactly what the othr guys do I could apply it.
It'* interesting to read his website. He seems brutally honest about himself and
other Chip burners. Please post the results of your dealings with GM tuners afterwords.

Also, was the 3 degrees of timing a guess ? Why not 5 ? How did you come up with that number ?

This should compliment your cam and valvetrain upgrade very nicely. Let us know how it goes.

I raised it that high b/c right now, it idles nice and smooth right there. 1000 is almost smooth but not really. (i'm runnin kinda rich )

Can't increase tranny line pressure b/c it'* vac controlled. I could get the B&M vac controler though.

I ripped off intense'* stage one timing.

I'll let you guys know how it goes.

Trans line pressure and shift firmness can be controlled electronically with the PCM changes even with the 4T60E. My Jet Stage 2 chip in my 93 SSEi has raised my line pressure to above factory specs, even with 110k on the trans. DrJay, too.

how many r'* can the tranny pump handle stock?

R'*?

I had shot him a couple emails when I was in the process of learning out the eprom programming.. and he was really nice. He was incredibly honest, and it was very suprising, because I could have easily taken the information he gave me, and used it to make some money, and take away some from him. But, I really don't know much about you guy'* ECM'* and such.. beyond me, mine only shoots an SES light and gives me ignition.. that'* really all mine does. [sarcastic yes, but in all truth.. it doesn't control a whole lot more].
