As far as I understand these are Lindsey Racing chips, but what stage are they?

LR/951MAX 9518687 DME 5151
LR/951MAX KLR 5152


Strange is that my fuel pressure is set to 55psi with these chips and as far as I can see my a/f ratio with narrow band, it's right where it should be.

noone?

LR stands for Lindsey Racing but they get the chips from Russell (used to frequent this board often). Lindsey's website:

951Max (Russell) is the manufacturer. His website is:

I'm sure that if you contact Russell he will answer any questions that you may have.

Our chips are not sold as Stage this or Stage that. We have many many files, and they are sold based on engine components and modifications. It would be impossible for anybody to know what those are unless they have our spread sheet logging what file that serial number references to.

That chip set was sold to a customer in Florida April 30, 2007. It's for a pretty much stock car including stock exhaust and cat with K26/6 and stock injectors.

Thank you Mike so much for your reply! Yes, I brought a car from this person a year ago.
May I kindly ask you to assist me in understanding do I need another chip at the moment?

1. Fuel pressure on this car is set to 55psi, but as I know these chips are ment for 45psi?

2. Should I replace or reprogram these chips if I have removed a cat and installed a performance exhaust manifold?

3. What should be approx. power figures for my chips?

Mike Lindsey

If that chip had been for a car with a larger exhaust, and no cat, it would of had more fuel mapped into it. That's probably why your adding fuel pressure now since it sounds like you running a better exhaust. If the a/f's are good (safe), then your probably ok as is.
