man i am telling you. this is the best mod i have ever done.the shifts are sweet and crisp.the power seems to be great.cant wait to take it to the track.so are yall still having to drive it for a couple a days to get everything to come around.please let me know.
-25% +25% 1-2 5650 2-3 5600 125 . i set my shifts at this since i was getting a sharp drop in power at 5800. now it shifts and lunges. i am very happy.

 

Isn't stock 5800?
So you lowered your shift points below stock??

 

see i never really got the point of lowering your shifts down. yea you might be losing power after a certain rpm but everytime you go into a different gear the ratio gets closer to 1:1. so why not stay in the 3.:1 and 2.:1 gears longer.

 

Glad to here it is working out.
Wow 99's got gipped. My truck stock shift points were around 5200 from the factory.

What years come at 5800?

 

factory shift on mine from 1-2 was 5400 and 2-3 5200.i set 1-2 5800 and 2-3 at 5700.when i tested it 1-2 fell off in power sharp at 5800.so i went a little lower.now it doesnt drop and man it really runs.my rev limiter is set at 5950.do you have to drive it for a couple a days for it to really come around. man if so i cant wait. hey chingon.how about that hpp3. man you really need to get the predator. i had a hpp3 in my 99 and the predator smokes it by fay.

 

Mine are also 5200 rpm. This is on my 2001 HD.

Glad it worked out for you. I couldnt be more happier with mine.

 

I loved my predator too until it fried my ECU and left me stranded 50miles from home! I would be very careful when installing modified tunes and would avoid EVER installing a downloaded custom tune from diablo. Thats what fried my ECU. Now im getting ls1edit.

 

Same thing happend to me!! I installed a custom tune on my truck and then went to install a "revised" tune and it wouldn't load it all. Truck wouldn't start back up later finding out that the PCM crashed. One look under the hood from GM and they saw my supercharger and they said I will have to pay for the PCM!! Fock Now looking into LS1 Edit

 

Toasted your ECU! That would make me super pissed! So now your Predator is useless now right?

 

Well toasted my PCM. Oh.... no... I am not mad I swear I just don't have alot of confidence in this predator, yeah it makes a good tune with a couple custom tunes my supercharged truck is screaming BUT, everytime I plug it in i wonder, is this going to cost me $500. I just don't understand if it is a program error... or just a once in a while blip of the predator.
