im running a mail order chip right now and its not to bad but not right i have a hard time to start up cold. blm's are not to bad little rich. with data login.
i have the moattes xtreme aldl cabl. and tuner pro rt. if i buy the burn 1 and some chips. would it hard to tune my combo. im running a 355 hsr and lt4 hot cam. with vette 113 heads..thanks.

 

check out the stickies above. lots of good info there on DIY tune.

 

get a W-B o2, they are well worth the money when it comes to getting it right and not spending a year to do it. Without a W-B you could be bad lean at WOT, I was and it cost me.

A MAF car is not that hard to tune if you have the right tools from the start.

Read the stickies untill you know them by heart, then read them again.

 

so get a W-B set up first. my tune is not to bad. im a little rich and cold start is not right.. i need to fix the cold start..and to see how my chip is set up..i dont know what the guy did. if i get a chip burner and some chips. i want work from the mail order tune. first i thought.. and buy W-B after.. what do you think. thanks.

 

It is always better to start with a stock BIN. Then tune from there. As you mentioned you and no-one here knows what was changed.

Work on getting the data logging up and running. Then start with a stock BIN and make changes for injector flow fans and what-not. Then tune from there.
