Hey All,
I've been running my Procharger HO setup for a few weeks and it runs GREAT except for one little issue. If I am around 2500 RPMs or so and get the pedal to about 60 percent the car surges multiple times until you either A. Let off the throttle, B. Go WOT, or C. Pass 3000 RPMs.
Here is what I have:
P1SC Pullied for 10 PSI at 7200 RPM
Stage 2 Intercooler
Brisk 1 Ranger Cooler Plugs gapped at .028
VMP Plug and Play BAP
Bypass Valve is the standard Butterfly BPV that comes with the kit
GT350 Manifold
I have been working with Lund who has said it may be the BPV but I'm not convinced as a 25 percent pedal accelerate from 2500 RPMs or so shows zero VAC and no surgring as does a WOT accelerate.
So far I have only received 1 revised tune from LUND that did not fix the issue and made 1st gear unusable in 1st gear. The other thing I have tried is replacing the 3/16 vacuum hose to the BPV with a 1/4 inch line (This included replacing the barb fittings on the vacuum black and BPV). This made no difference. I also tried moving the vacuum block from the factor vacuum tree to the stand alone port on the manifold (Port where the break booster connects on GT350 Cars)
I am at a loss here? Should I continue to push LUND for a tune? Has anyone upgraded to the BIG red race valve and had it resolve the issue?
