Ran the car tonight at the drag and got a limp mode almost every time after letting off in 5th gear. I didnt have a c reader so i couldnt see the codes.

It appears that all piggybacks are susceptible to Limp modes...this is a fact of life. The question is...how often?

Secondly, there must be a wire installed incorrectly. If you say you were gettting a limp mode almost every time after letting off in 5th gear, does that mean they were clearing themselves before each run and then coming back? Without a C-reader, you cant clear them, so Im confused at this.

This is a rare occurrence and one Im chalking up to install error. This is a limp-free piggy back.

You went to the drag strip... and got a limp mode in 5th gear.. For what reason was your car in 5th gear on the drag strip? I try my very best to finish in 3rd and almost always in 4th.. My 4th gear goes up to 145-150.. what were you doing in 5th?

his limps were happening on decel not acceleration i am suspecting stuck or sticking bypass valves... we dont make any changes on decel FWIW either way we are communicating with the owner and trying to discern the issue. He has forge valves and they do require maintenance on occasion, they may possibly be sticking or a different spring tension may have to get used.

I can hopefully tell you after tomorrow. New boost gauge is going in. I was told low-mid 14s at highest....mostly in the 13's. On race gas it should hit 15psi or so.

Trapping at 105 on 93 octane!? And you say the car feels fine? Am I the only person who thinks that's low?

It was about 57 deg out maybe a little colder. I saw your post about your times. Thats why im really not happy with these times. What tires are you using? Im on stock RFT.
