Update: 14th

 

My use of mail order is a bit misleading...I found a local guy with the help of these forums that does what he calls a pcm edit for 70 bucks. A couple of others from here vouched for him, and I figure for the money I can't go wrong...my thinking is that I don't need a full dyno tune with the stock'ish setup. He says his pcm edit is the equivalent of a mail order.

 

ah, cool beans.

 

Dunno at this point, I think their tracking is just screwed up. LOL

They say it left on the 11th (phone tracking) and wil be here Monday.

Their web page tracking says it is leaving today and will be here tomorrow

Who knows

 

i want to know more about these mail order tunes~~~

i was always told bad things about them but it was for my wifes modded LS1 car, they always said you needed a full tune due to the changes....

well my question is , i want one for my truck, basically a stock 04 GMC RST, dont know if they changed any computer stuff or not, but i do tow a trailer with 2 mowers on it during the summer, but yet i want to get the truck to run a bit better~via..mail order tune, i quess being a stock tune it would be easier to tweek it,......who has had one , who did it , and was is the pros and cons,.....i do planning on keeping the truck stock untill next year whem im doing full exhaust redo,.(headers,y-pipe, o2 delete, and cat delete) which i know it will need tuned then,...just looking for a little more power untill then..

thanks in advance, Boog

 

My understanding is that until you go with heads, cam, forced induction, and/or N02 a mail order will suit a person fine. Pretty much all they are doing is adding or pulling timing and adding or leaning air/fuel, and for automatics they can change shift points and firmness and modify torque management.
I'm sure a tune can be more dialed in on a dyno, but for the extra money additional gains would be negligible imo.

 

do you have one RST?(mail order tune)

 

Not exactly, and not yet lol...going to see this guy this coming Monday, and I hope to dyno it toward the end of this month.

 

oh,okay, keep us informed!

 

It's in MD about 60 miles away from my place. Should have it in the morning. Replacement wing got here today. 04 tails hopefully in the morning too or Monday. Unfortunally I don't have tags for it.
