Can anyone provide a mail order(email order)HPT tune? I have a 2000 SS with a 408/4l80e and I am in need of a tune. The car was previously dyno tuned by ECS with a SD tune but the cold start is very lean and it needs help. The car has a very big cam and not a lot of vacuum so I thought a MAF might be a better way to go. I have HP Tuners so I am only in need of file as oppsoed to sending the ECM in. I know that a mail order tune can only get so close but that is fine because I only need a good starting point. Thanks

I attached a copy of the tune and a short datalog of a cold start. Unfortunately the data log doesn't have the WB02 data with it but it agreed with the nb02's. The WB read between 17-18 until the coolant temp got to around 120 then the a/f dropped down into the id 14's. The car has a BIG cam it which is making a little tougher to tune. I went ahead and listed some of the engine basics below. Any help would be appreciated. Thanks

Did you get some help with this?
As stated it's lean during warm up, your Open Loop EQ Ratio table is where can make some changes to that.
The STFT's go very positive once they turn on, in the area of 20%. Not knowing what you are using for a MAF table, maybe increase the entire table by 20% moving the entire table by the percentage needed to bring your STFT's @ idle into line. That may help rough it in so you can get it rolling.
