I have run into yet another problem. I am accelerating in any gear and hit around 3-3.5 k/rpm and it starts to sputter and doesn't feel like pushing anymore after that. Thought it was my plugs... They were messed up and changed them... wasn't it. I noticed this happens right near the time my car hits 10 lbs on the 1st turbo. Please help I want to go have some fun this weekend!!!
Here is my mods:
RP Streetported motor
Pettit Highflow twins w/ clipped turbines
Power FC (Supposedly tuned fairly rich w/ my timing retarded to drop power potential)
Apex'i FMIC
Jacobs ignition and coil pack
9's for spark plugs
850's all around
High flow fuel pump
intake, exhaust, high flow cat

Please help!!!
Thanks,
Ryker

 

wassup man, have you moved your battery? could be a grouding issue.. try improving the ground to the car from the batt, to the engine, the chassis, the tranny. This might solve it.

it might be that your second turbo is not kickin in

 

It will do it before it reaches the spool rpm's for the second turbo. Battery has been relocated to bins. (This can cause a problem w/ acceleration

check to see if all your hoses are connected that is the problem most of the time, and where are my $10??? jk keep the advice and the money, make sure you check the hoses everywhere not just on top.

 

Maybe you're just running too rich, causing the engine to sputter. How does it run in the higher RPM's?

 

Second turbo? You went back to twins? Is the PFC tuned for the twins or the single turbo kit?

 

his sounds like the classic 3000 RPM hesitation. I think the only way I have really seen this solved, consistently anyway, was the installation of stand alone ECU like the power fc.

 

Do what Ninjak says, i just went through this problem and could not figure it out. I grounded the block in 3 different spots and it was fixed, no more sputtering and backfiring.

 

It sounds like a problem relating to the secondary injectors. That is about the time that they are coming online. I would double check that your PFC knows you have different injectors.

 

it may be in limp mode. disconect the battery, hold foot on brake for 20 seconds, let sit for another 2 minutes, then reconect it, and viola. pm me to get my info on where to send ten bucks

 

I'm running a Power fc that is tuned! If I reset the ECU I lose all of my tuning. That won't do. I'm going to look over my hoses... hope that is it. I am also only holding about 11lbs of vacuum at idle. hmm.... I'm wondering which hoses to start looking at considering there is quite a few of them.
Thanks for any help,
Ryker
