Hi guys

I would like to know what are your air flow readings with a gen2 and ls1 maf with an extender extreme chip. My scanner reads 246 at full throtle and would like to know if that is normal.
Thanks,
Marco

Sounds OK to me.....you gotta remember that you need to triple your air flow numbers on the SM when using the Extender Extreme Chip!

What did you read those numbers on? The Scanmaster or GenII?
 
Man I've got to get mine tuned. 6.65 in the 1/8th. I am jealous. I might have to call you for some tuning advice. How much boost?

I read those numbers on a OTC 4000e scan tool.

WOW ,when you work out the bugs this could be a 9 second contender.

Hi Bob
I wish but I don't think so, maybe 10.30 to 10.50 with the fuel issue solved, depending on the 60 ft. I still have the stock TB and plenum, but if I would upgrade those parts and with a 67 mm turbo I think I would get really close. If I would switch to real slicks instead of drag radials so I could launch the car at atleast 10 lbs of boost, I wouldn't be surprised to hit a 9 then but my stock rearend wouldn't last that long.

I am running 22 to 23 lbs in first, 23+ in second, and 23 to 25+ in third.

So, your actual MAF flow is 738. Seems high to me, based on your boost, etc.
