My point is that the stock tables *should* work fine... Messing with them is probably what screwed it up. Do you have stock cams?

yes stock cams, but 60# injectors

Also, the fuel system is a return style now, not a returnless...will that impact it?

If the conversion was done right, that shouldn't have hurt the cold starting... if they modified the tune right. There are lots of ways to modify it wrong and screw things up.

Sorry about the lack of pics guys, the weather has been SINFUL here lately...extreme cold warnings and all that...I have not forgotten!!

Well i know that the shop needs an accurate AFR reading RIGHT on startup to tune the cold start correctly. Its probably starting too lean right away. Im supposed to be taking her back into the shop today as my mechanic got a portable wideband kit to temp throw into the car that will give him a reading as the engine is cranking...my lcd screen with my afr gauge takes 40 seconds to load...hense the need for the 2nd temp kit. Im sure we will get it figured.

What he actually needed to do was not mess with the stock cold start enrichment curve.

Are you using the stock MAF?
4thfiero FEB 23, 11:41 AM
Ill double check of the MAF, i cant remember. lol.

Sorry again for lack of pics...we have had a bad cold spell here...its FREEZING...i dont wanna stand outside and take pics lol. I promise as soon as it warms up a bit I will

Will: No it doesnt use a MAF it uses a 2 bar MAP from gm.

Doesn't have a mAF at all? Interesting. I see your shop chose the hard way repeatedly...
