well the shift kit, vette servo and 4th gear servo are just going to change your shifting characteristics. you wont notice any increase in power. I would recomend upgrading to a higher stall torque converter so you are a little higher up in the powerband if you plan on furter modding in the future.

mikel are we talking obd1 or obd2 emission testing? if they do tailpipe testing(obd1) then yes it will insta fail beacuse there are no cats. with obd2 as long as all the rediness monitors are completed and the cel is off, then it'll pass emissions. tons of people go through emissions with no cats ...

i would advise renting or purchasing a fuel pressure gauge. This will tell you for sure what your pump is doing. LS1's have a test port on the fuel rail to tap into to test for fuel pressure.

if you dont have someone to ride with you to watch for KR, save the log on your predator and you can view it after you make your run.. When i am adjusting wot timing i will just log RPM, spark advance and maximum knock retard. The log viewer is a pretty simple feature to use and works quite well ...

yea go look at 'downshift mph' in your modify parameter section. ALso, did you adjust your WOT fuel? what about your ignition timing? these will both help you pick up a little bit more power.

the dsp will let you raise rpm limit to 6600

advance the timing from 1-1.8K range. I advanced my timing a few degrees as waas able to roast the tires

corey getting headers for a naturally aspirated engine is one of the best mods you can do. Long tubes would be the best bet and depending on where you live, you might be able to run without cats(if you want). As far as the electric fans go, thats going to free up 10-15hp since those fans rob a good ...

my current lockup is around 40 or 45mph. The engine drops down to a pretty low rpm but it isnt lugging it or anything. Would i be fine not having this adjusted?

what do you mean the stall speed mph? sorry i am not really understanding what you are saying.

bump for mod to look into

not in my truck, i can bring it all the way up to 6k if i want to.

while i am in park, when i go WOT it will limit to 3500 or w/e and bounce off the limiter.

hey monte, dont mean to steal this thread, but is it possible to have for my 02 sierra with 5.3?
