ok i have a 05 silverado with a 5.3l w\ intake and magnaflow catback and i want to get it tuned for some extra hp..when i get it tuned how much TM should i take off and how much is safe. all im planning on doing to the truck is pullies and tune and thats it i want to keep the trans in it and not break anything..please tell me what i should get done in this tune and what should i look out for to keep my truck running for a long time.another question is when im on it and it shifts to 3rd the RPM's stay at 3500 and dont move untill i hit the speed limiter.. i was racing lastnight and was neck and neck with another truck (has a nelson tune) and as soon as i hit 3rd it was like i got off it and he blew by.. is this something with TM and can be took off with a tune or is my truck just week.. ps the other truck was a 4.8 thanx for the help

 

Since you dont have a shift kit you should probably only get 70% TM removed. Shift points should be good at 6200 since you dont have a cam.

 

why so high wont this damage my engine?

 

5800 rpms is all you need since stock cam falls off after that.

 

thanx

 

I would not set my shift pionts at 6200 with stock cam.

 

i got mine set at 6200 with my stock cam. it pulls hard all the way up there.

 

call and talk to allen and he will get you set up with the right shift points and all.

 

yeah i talked to him and it all sounds great but...i have to mail him my computer for a tune...so i might have to go with a preditor.. :-(

 

The way it works with him and most mail order tuners: You order your tune, he sends you a new PCM with the tune on it. Then when you swap them out, you send the old one back to him. The only down time is the 5min it takes to swap PCM's. You do have to mail your old PCM back to him, or you can keep it and pay the core.
