Well I went and had Flaco Tune my 97 and it put down decent numbers. Or I feel they are decent.

Mods Are:
1997 C1500 5.7 Vortec
0411 PCM
Whipple Super Charger
36# Injectors
255 Walbro
2 Bar Map
Long Tubes , True Duals, X-Pipe
Accel Coil
TR6 Plugs
CAM
BeeHive Springs

Stock Trans
3:42 gears - 275/60/15 Tire

Put down 324 to the wheels @ 5# of boost
He said close to 450 in torque

Now I am working on getting my trans built and maybe 4:10's ???


Would 4:10s be the way to go ??

 

What does Flaco have to do with this post?

 

Curious... what do your fuel trims look like at idle and cruise?

 

Doubt he got a glimpse.

 

Werd.

 

he tuned it

 

just saying he tuned it! Thought I'd share! Is that so much of a problem? He's a hell of a Tuner and a nice guy, just sharing my experience and asked about some gears

 

Not sure bud, I didn't see.. all he told me was my injectors where at 70% duty

 

Flaco tuned my truck. Put down 642 to the wheels. Drivability was a world of difference better over the N/A tune. No surging, trying to fkn die when turning, etc.

I would not go 4.10s, if it was my truck. I'd try going with a shorter tire. You have the low end with the PD blower.

Not sure how the trans is still alive

 

BTW, tuned by flaco is the sticker in the back window of a lot of trucks in the Houston area. Explaining the title of the thread
