Where to start with LS1 edit? I have bolted on an ATI P1SC1 to the 99 LS1 and was wondering where to start tuning with the LS1 Edit? Mods are 2 1/2" dual catless exhaust 160 stat aeromotive rising rate pressure reg BBK 255 LPH in tank pump all running with the 3.25" pulley. Originally I was going to go only 4 PSI but I got my *** handed to me by a Turbocharged Honda Prelude that I built for my friend( dont laugh the damn car put out 345 to the front wheels @ 15 PSI) I am on the fence as to which injectors to go with as well, and where to purchase them. The last question deals with how much boost the stock LS1 can handle on good gas and A good FMIC,which I have installed. Any info on these especially the LS1 edit parameters that you guys are running would be great, and would help me beat the 2.3 rice.

I think the rest of your questions can be answered by doing a search.
My opinion is the 42# bosch green tops (ford svo) are a good injector, people here say they are good for 600rwhp. Look on ebay for a new set.

Re: Where to start with LS1 edit? If you are looking for injectors, i would go with a set of delphi 36#'s for what you got, VALVEGOD sells them pretty cheap, and they are brand new GM pieces, i got a set, and they are working fine with my setup. Give him a call @ 248-276-0483, his name is Shawn, and is a great guy to deal with, tell him that Jason from Mach Performance sent you, he'll take good acre of you on any LS1 oem parts you need.

Re: Where to start with LS1 edit? I'm in the process of tuning my ati kit now as well. I've got it fairly close, just tweaking left. I've got the fuel system in my sig. I initially took my last edit file, and richened the pe vs. rpm table and dropped the timing a lot since I had read about the low timing a lot of other people have with FI. Long story short, it ran like *** for a week and a half in wot mode. So I went back to just a stock program calibrated for the injectors. That was lean from the get go at part throttle, so I dropped the flow rate table until ltrims came in line (almost all the way back to stock <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> ). Worked great. I've since dropped the timing 4 or 5 degrees to be safe and added 5% to the pe table. Once I'm comfortable that I've got it right, I'll upload it to ls1edit.com. PM me if you'd like a current copy of where I'm at.
BTW, I've got a 160 stat too, but haven't put it in yet. I remember a post in the tuning forum about a month back with fan temps for that tstat.
