Default ls2 injector data for ls1 pcm

I will be using a complete ported ls2 intake setup on my 99 c5 and was wondering if somebody could tell me what the injector data for using stock ls2 injectors with a ls1 pcm is? there is a thread i found on this on the hp tuners forum but im not sure which to use. also what should be changed when going to the bigger ls2 tb?

I have attached a copy of my tune. It is nothing right now but turning the codes off for the headers. I have not put in the cam or intake setup yet but i will be as soon as i get home from germany. I am just trying to get my ducks in a row now so it will go as quick and painless as possible.

thanks for your help in advance.

Go here: http://www.tunefiledepot.com/index.p...Type=P&Stock=Y

Download a tune for a stock 2005 6.0L GTO, copy the injector data from that tune into yours.

I've a tune in the achieves for my C5 with those injectors, I can dig that up & forward to you. Send me a PM with your email if interested.

There is not much in the LS2 intake power wise if that is your goal. I went thru that with my LS2 stock & ported. Find a FAST 92 then get it properly ported if you want some worthwhile gains. The FAST 102 works very well, the problem is will most likely contact the firewall. I shimmed my cradle for clearance.

Grab a stock LS2 tune off the HPTuners website. The data may be slightly different.

the injector data is scaled different in a ls2 pcm. here is what i came up with not sure its right though. ill pm you ctd. only reason im using the ls2 setup is i got the whole intake, tb, injectors, and fuel rail for 250. ill port the tb and intake and it will hopefully make a little more than a ls6, it will definitely make more than the stock ls1 intake that is on there now.

Yes, that looks correct.
See what CTD file says.

But you copied correctly.
