you're going to have to define "running rich" at WOT? you have way too much fuel and heads for a TA-49, so you may need to play with fuel pressure to make it work...your combo really needs a much bigger turbo

 

[rob nolan]

Well i'm still running a stock converter and i drive it on the street alot i don't want to have a lot of turbo lag for right now BUT this winter i'm gonna put a converter 3200 to 3500 stall some where around there and then i'll go to a biigger turbo what size do you think i need to go to thanks Rob

Are the chips you are running burned for your new 55# Injectors?

 

[rob nolan]

chips

yes they are i had them done the sametime as the ecm

I am sorta paritial to Limit Eng TE-45A.......you'll want 3600 stall for it

right now, you are prolly drowning your motor in fuel...be sure and tell Red what turbo and heads you are running and maybe he can compensate

when are you kicking the 2nd pump on? maybe disconnect it until you get bigger turbo

Yeah I think you would be much better off with a TE-45A or TE63 turbo with your combo cause 55's are a little much for the 49 turbo (42.5 or 50lb injectors are a much better match along with a single 340 walbro fuel pump) IMO. Also you mentioned that you have a 106 chip for the track and from what I've heard that chip has low timing which means you will have to run a LOT of boost to get the most from it. I know a couple of guys that use Red's 106 chip and they both are running around 35lbs of boost ........... so you would probably be better off with Red's 108 chip which has about 26deg of timing and should work fine with about 22-25lbs of boost. Just my 2 cents

I had mine down to 38# line off last night with 25 lbs of boost and 1550-1600 EGTs, 0.7KR.
