Mine did the same thing as his, runs fine cold but bogs down when warm and continues to bog more. Sometimes it would buck. go past 2 to 5 % throttle and it'll feel like you hit the brakes because it would stop accelerating. at that point the blow off valve might go off too. The more throttle you give it the more you go nowhere fast. You might hear it pop or knock once in a while. At first I thought it was the fpr because at full throttle, fuel pressure would max out my gauge at 60psi. maybe it's running rich. I have a walbro on a stock fpr. Got a new fpr and now pressures are correct now. But it didn't fix my bogging issue. rerouted my blowoff valve lines, fpr and boost gauge vacuum lines. Figured out for each of the lower nipple and the right nipple when you are looking at the engine from the front of the car, only one sees vacuum and the other only sees boost pressure. But that didn't fix my bogging issue. Found my tps sensor signal voltage would drop out during its sweep and replaced it. But that didn't fix my bogging issue. Checked wiring to O2 sensor from ECU and tested O2 sensor with torch, everything was good. ohm-ed the coils at operating temp and that was good. Checked spark plugs - good. Bled the lash adjusters. Nothing fixed my issue until I went to time it again for the millionth time. I figured out my timing light pickup when I hooked it up to the loop at the back of the engine was too close to other wires and was giving me wrong readings. Now I'm boosting 11 psi at operating temp.
