I know the answer is a reburn, however I wanted your comments.

I have just purchased a chip with a program that incorporates: Full exhaust system, 90mm MAF, stall converter, ported upper intake, and a 6lber.

My mods are: cat back only, C&L 85mm MAF, and a 4lber.

Will this chip do harm to my L or is it a safe tune for me???

 

It will probably work, but to be sure any chip is safe you might want to get an egt gauge and a wideband O2.

 

reburn, with the wrong MAF and the wrong pulley that might be pushin a lil bit too far

 

since he has the C&L that may make the tune a little lean, but he also has a 4lb instead of a 6#.

 

ah ya good point, i was thinking backwards on that one.

 

id be concerned what the timing is set at more than anything, really what fuel its burned for. if its burned for someone who has 94 octane fuel and you run 91 that could be a big problem. the converter would seem like the next big issue.

 

There were not line pressure in the program, will it still matter with the Converter?
