I have no clue why my hpfp values are still over but a couple hundred I'm not sure if this is normal or not. My last hpfp was so bad it would dip down to 900-1100 under wot. Just recently got a new one because of that issue. I'm only running stage 2 it's bm3 I'm pretty sure the hpfp should be more than ok. Car has 21k miles. Any input?

The HPFP values are dipping but don't seem to be in dangerous territory.

Timing corrections seem pretty high for a 91 tune - how's your fuel quality?

I'm using 91 but I live in California so my guess is not good at all. Just weird how my hpfp values drop that much ok 91 with only 20k miles. Spoke to bm3 they are saying it's not right either. Also spoke to Jordan tune and he was saying that's not right either. Just order a new precision raceworks lpfp so let's see if that helps.

Are you using the ACN tune? if not that's probably your issue. California gas isn't just 91, it's the worst possible blend of 91 they could make and legally call it 91.

Try that because the timing doesn't seem right perhaps bad fuel?. I'm on Stage 2 ACN 91 and I don't have the same issues. I'm in socal as well

Which HPFP do you have? If aftermarket, do you have it selected on the map configuration?
