I'm pretty sure one costs 1/2 as much as the other. and if they both give you a great tune then save the $250 and get the cheaper one. Then you'll have money to spend on something else. and if you still can't decide, and thats still too much $$ check with Zippy, costs less than both of those and has great results. Not knockin the others, just My .02

 

Well, to be honest there is a $100 difference. But i also hear that you get what you pay for. Trying to get all (if any) of the problems pep's have had with the PCM's they have got.

 

dunno if youve looked on gmfullsize, but justin has alot of ratings over there.

 

+1 for nelson my 6.0l runs like a champ plus im getting alot better milage..if i lived in texas i would go see him.. hell i might even take a drive down there next year so he can install cam and springs and do a live tune..

 

i guess since laynlow mentioned ill add +1 for justin (blackbearperformance) too. i first had a nelson mail order tune and as far as i knew it was great. but after tuning with justin in person there were a few things he was able to adjust that made the truck run even better. food for thought. although i would say in person tuning or dyno tuning is the way to go over mail order anyday.

nice thing about using justin is he has a logging device to exactly see what your truck is doing versus doing a canned tune just off of mods given.

 

That is true, if (and i might) take the drive and get the in person tune. This is always the better choice.

 

Since i do have the stock 4L60E, Nelson recommends 80% max reduction in Torque Management. Has anyone here lost a tranny due to 100% If so what went out?

 

ill also add this. im sure he isnt the only tuner that does it but nelson locks his tunes and you wont be able to have someone else tune it after the fact if you change your mind or decide to get another tune. cant speak for wheatley or some of the others.

 

So, does Blackbear lock theres?

 

I'm in the same boat as which mail order tune to get, in two week's I will be installing my cam and then I will NEED a tune. I just can't decide what one to get, Nelson or Wheatley.......?
