Dyno
 

anyone with a 5.3 with a small cam that has a dyno sheet and is
willing to share ? i am looking to compare it with mine. I am getting
a new tune and want to see diff tune results. if you don't want to
post it you can e-mail it to me, turboal@aol.com no one will see
it but me. I need all the help i can get . thanks in advance AL

4300rpm, 255hp, 310tq(peak)
5575rpm, 300hp(peak), 285tq


5.3 with isky triple 12, heads shaved to get 10:1 cr, cai, efans, and this was with a base tune.

If I had to guess, now Im more like 315hp@6000 and 330ft/lb@4500.

Shifts are now 6300 and pulls great the whole way.

tune
 

my base tune was 285hp/6350- 294tq/4000 on 87 octane and 95 deg temp.
going back when it cools down a little with 93 octane for retune.

Here is an old one I did many years ago. If I remember later we cut the cats off and put on a K&N hot air kit and I thing we got the RWHP up to a little over 320.

tune
 

that is outstanding, i would like to get that out of my swap.
do you still have that tune file ?

Haven't dynoed yet but did just install a Cam Motion Stage 2 drop in cam for testing. 205/210 .510/.510 115+4

Baseline was 220rwhp/240rwtq for a 2nd gear pull unlocked converter (stingy dyno).

Maf values went from just under 29 lbs/min to 34 lbs/min

Full review will be up as soon as I get back on the dyno and get some MPG numbers

99's have like 19 lbs/hr injectors from the factory. If you haven't upgraded, then that could be holding you back.

Injector duty cycle is at 88% WOT. I have a set of the later injectors I can put in. But I will probably wait until I put on headers and retune for everything at once.

Not really concerned with the numbers, dynos are just tools. I have seen a head/cam/full bolt on ls1 car with manual transmission make under 400rwhp on this dyno.
