CTS-V fuel pump in GT/G8

[ZiM]

I'm getting ready to install the CTSv pump into my G8, (will order tomorrow) but i'm wondering if you guys did your back seat pump cut-out access hole with the tank removed, or just followed what seems to be an outline...??
I'll be running the 2300 maggie with ls9 injectors. Also have the livernoise cam and LS# head package.....any suggestions would be help full...thanks

Also, long shot, but does anybody have a canned tune I could use..I have HP tuners, but never really learned how to tune myself....just need a tune (or advice) how to get the ls9 injectors to fire with the new ctsv pump...just enough for me to get to my tuner....

It would be worth it to pay the little extra for a legit tune

Hope what I sent you worked out great. Good luck on the build, but those Injectors will not be enough

thanks thebeast, haven't had a chance to upload the file yet as i'm still waiting on a few parts from Greg and Carol....should be all done hopefully by mid Sep. Thanks for the tune...again, it just needs to get me to my tuner...I really don't feel like swapping out my stock injectors and puttng in the LS9 injectors when get there...rather drive to him, tune and drive back....

Why you say I need bigger injectors...?? I know you told me...but i forget

Let me know how that ZL1 pump install goes...Might be needing one SOON :O

My injector duty cycle on the ls9 injectors was 106 at 5900 Rpms, wasn't making anymore power after that. Safe limits are around 85% or so. You should be around same power level as myself(630rwhp or so) and they just weren't enough.
I now have 60lb injectors and at 6600rpms Idc's are 81%.

Will do. I purchased all the parts i need from Carol at vaporworx and the kit arrive the other day. I'll post some pics soon. Looks likes a tight, factory looking kit.

You can run what you have and see where it falls. Your fuel pressure will be higher than mine because of your pump, so your idc may be different.

It's up to you. Run what you have for now and see if you really will need Injectors.
