I have a loss of low end power after PIH conversion, please help!!
 

I am having a problem with a loss of low end power. If I punch it from a stop it acts like it is bogging, sometimes it even pops. When it bogs, I let off of it and then nail it again and it takes off. If I use my trans break and stall it to about 2800 it bogs down and takes off slowly. These tests were done on street tires. But once it gets past 3500 it really screams to the red line. I am at a total loss. I had the fuel set at 45psi. It didn't run well at all. I then went down to 40psi and it seems to be better, but I don't know why it would want it that low. When I had the stock computer I could punch it and it would really burn street tires. Another thing I also noticed was that when I would get on the trans brake with the stock computer, it would stall to about 3200. Now it will only stall to about 2800. Does anyone have a clue about what is going on?? I am lost. I don't know where to go with this. If anyone has ANY ideas, please let me know. I want to get the car running right. Thanks.

I guess no one has an idea about my loss of power? Damn, I wish I could fix this. Thanks.

Billy, the A9L's more agressive fuel tables might possibly explain the need to lower the pressure. Where is your base timing at? Have you contacted Pro-Flow about this?

Well, I would call pro-m, but I have done somehting that they probably wouldn't recomend. I have their electronics calibrated for 24# injectors on top of the C&L meter, which has a 24# sampling tube. I don't know why this would make this much of a difference. I really wish I had a dyno close by so I could see what my A/F is. It seems like it is pig rich down low and lean up top. I don't know. What do you think? Thanks for your post though. No one else seems to have a clue. Kind of odd. Oh well. Take it easy.

I would imagine that they would say thats the problem, just to get you off the phone. Never know though, if they can give you some kind of logical explanation on why it wont work, it would be worth calling. If they tell you it wont work 'just because' it would probably just be an attempt to get you to buy their meter and get you off the phone.

$450 is alot of dough to fork out for a pro-m 77, but I think they are worth it.
