Nice numbers. How do you think the traction issue will be with 2wd? I would think its your return line keeping the psi up, that and the two pumps. Nice setup though. Hopefully you'll get it worked out. Wheres Parish....

 

well with the 4 link in the rear it feels way better launching
haven't really been able to mess around with the suspension much

I'm gonna have to mess with the pressure switch and set it up too turn on at a higer boost level some where around 10psi i figure
somwhere around there is where i will need the extra fuel

How much Hp will one 340 support i wonder ?

 

Nice numbers! Did you log G/cyl in EFI live?

 

here is a screen shot of one of the runs

 

hey gmc what size injectors your running, and did you change you fuel pump?

 

I'm running 57lbs injectors from siemans
the Fuel pumps are From racetronix 2 walboro 340 pumps
one on a hobbs pressure activation swtich

 

You have all the torque management stuff taken out, right? Like max torque set to 639?

Whats your High octane table look like, mainly in the bottom third of the table from idle to redline? I know the stock table actually drops to zero and below zero when you really start pushing air.

Do you have the Knock learn disabled so it doesn't look in the low octane table?

Also look in IAT vs load and make sure its not pulling too much timing for your IAT's.

 

Got the Edit file you sent me, and judging by this screen shot, your IAT's go from 100-150 degrees during the run. Your edit tune pulls 7 degrees at 100F, and 15 degrees at 150F.

Get that Intercooler tank on there, and get those IAT's in the 80-100 degree range, and you should see 5-11 degrees more timing through your whole rpm range.

Other than that, your tune looks good. Its just pulling timing because of the high IAT's.

 

Thought i might have something to do with it
whay Table are you looking at to see those numbers?

 

IATvsLoad table. That table is in Celcius, so you have to convert it.
