I'm running into an issue after doing the 2nd Gen swap and a revised tune.

It almost feels like a fuel cut which I did get a relief valve activated two times.

I bought a rail plug and have never come back, but did a data log was told my CP3 was getting weak, purchased with what I could afford II, and new injectors.

Did another data log.

Again, I was told you are losing the FRP sensor connection.

Purchased a new one as well with a new connector, same thing.

FRP gets to about 25k with no issues but with easy throttle.

If I floor it from a standstill, it will buck left and right.

Even on level 2 on the CSP5 SOTF switch.

Could this be a noob mistake on my behalf or just a tune issue?

No hard starts, no blue smoke, and very light black smoke 100% TP which i find very strange.

New connector tubes, CP3, lift pump, studs, hg, S464 kit all of this went in together, all torqued to specs
