First off, I have read every thread that has anything to do with slow spool/boost recovery. I think in one of the threads the guy had the same issue as me but he gave up after about 4 pages and I think he just sold the car.
I have an FP3082HTA and I don't hit full boost till around 4,700 RPM when I should be hitting full boost in the 3,700 RPM range. As much as I hate the late spool I hate the boost recovery even more. When I'm doing a pull I will hit full boost (I have it set to like 21psi right now but normally around 30) and when I shift the boost gauge drops into vacuum real quick then when I hit the gas it will jump up to 10 psi then it will take a 1 1/2 sec to get back up into boost. I have been having this problem for a long time.
My mod list is current, however I do have ECMlink V3 but I wont be hooking it up at all until tomorrow.
List of things that have been done and that I know about the issue:
There are NO BOOST LEAKS.
Compression is good @ 145, 145, 145, 150
Leak down test was good.
I have taken apart the tail 44v wast gate. The valve seat was there and there was no rips in the diaphram.
We installed a MBC in place of the EBC and it did nothing.
We have ran WG pressure and the problem is still there.
We have verified base timing numerous times and even pulled plug one to verify it with true TDC.
We removed the adj cam gears and replaced them with stock gears because the marks on the adj ones were a little weird.
We completely removed the exhaust and did a pull like that and it didn't help the problem.
We blocked off the HKS SSBOV and it didn't fix the problem.
We checked PSI from the lower intercooler pipe against PSI from the JMF SMIM and it only showed a 2 psi drop during spool up and no difference when in full boost.
I think that is it but we may have tried more. Any help would be appreciated. I am at the end of the line with this car and this problem. I'm going to try everything in my power to figure this out until July first, after that im tearing it apart and crushing the cursed shell.
