I got some good numbers sunday 425 hp 414 ft lbs.A friend has some 37 lb injectors i would like to use them if any one has an edit program i can use, would really appreciate it.I'm waiting on the last few parts to build the aftercooler& another set of asm headers,the first ones leak on the right side,and the left side hits the steering shaft.Anyone have problems with thier asm's? Thanks in advance.

 

some good numbers Have you done some tuning on it yet ?
How many Psi Are you running with yor setup ?
what injectors are you running now?
37Lbs injectors which ones are those ?
I'm curious to see your dyno Curve
Did you use the stock bore of the 5.3L?

wont help to have anyones edit file, you just need to adjust the injector flow rate. i think the calculated number for 37lb injectors would be 4.6gm/sec. try that number and see what it does to your ltrims. if they are way off adjust that number.

 

Gmc ski,yes we did some tuning.A good friend has tuned with other programers,he's getting into edit.We saw 12 psi,using stock inj. 37s are svo,a friend had on his twin turbo vette at one time,{he put down 596 hp,739 rwtq sunday}.We are gonna post the dyno sheet tommorrow.
