Honestly, talk to rob or pat about that. I was going to do that soon with my truck.

 

OP :
What size pulley did Maggie ship with ?
Mine came with a 3.7" and makes 6.5 PSI
.
Recommend you obtain HPTuners, and install wideband O2.... I don't know how you could possibly be happy without ability to tune your truck.

 

Mine came with a 3.4" pulley. I have a 3" on the way. I Will be getting a HP tuner pro and most likely have Atomic tune it. I have my cam and all my parts now just need to get to work.

 

Somebody ring?

I sell the interfaces also below retail if you are wanting/needing one. I cant post the price online, but its worth your while

 

On Blackbear I will leave this here...... we got a truck he had previously tuned with a TVS 1900 on it and it looked to be pretty lean on the wideband. We pullied the blower down to a 2.8 from the stock pulley and added a 90 mm throttle body. When we inquired on him sending an updated tune ( offering to pay of course) as he would have the original file from the truck his response was "my tune will be fine with the changes"..... uh huh. Didn't really care about the engine anyway ( pulling it ) so just decided on saying to hell with it and run it...... yeah the second pass at the track it pushed out a head gasket and was running dead lean......

Responses were once a week on average.... find someone else.

 

Blackbear is a small company with only a few employees so if you need tunes immediately they probably aren't for you. I like them myself, they've helped me out many times but I have learned to be patient especially if they get busy with on-the-road tuning events. You would be hard-pressed to find much negative about them online though. Great people and service IMO. I use the Autocal so it's a bit easier for me to get tunes from them but yes it takes a week.

 

It's mostly because people that don't own tuners and or the autocal is why you don't hear a lot of bad stuff. Those people just do not have a single clue what they would be looking for in regards to a bad tune.

I've seen a file or two before, wasn't impressed and same with other tuners on various forums with similar opinions.
