Hey everyone. I have a fully built ls hatch. I got it tuned about a month ago using crome gold. Anyways my shift light was set for 7300 and redline for 7500rpms. Its been cold the past couple weeks and the last week I was having some issues with it cutting out after it ran for a few minutes. Recalibrated my tps and that solved the problem. So on the way home from work today some turd pulled up to me in a v6 mustang revving at me. So I decided id give him the sauce. Lol anyways we took off. Went through first gear and I hadent looked at my cluster yet as I knew I was no where near 7300rpms. As I went to glance down it redlined. No biggie. Threw it into 2nd. And now im more focused on my tach. 4k,5k,6k, the 6300.....shift light. Followed immediately by a redline before I could shift or let out. Anyways my question is why and or how did my shift point move down 1000rpms?!?!?! Anyone else have this problem? I knkw it was set correctly before because ive had it to 7300 before.

 

crome gold shift points change based on gear. check with your tuner, he should know exactly what's going on based on how it was programmed.

 

Don't forget that the stock tach is terribly inaccurate in the upper revs as well.

 

it's not that inaccurate if you use a grounding kit.
