Interesting development: I had an issue with the Teg over the last few months. She was getting sluggish, and vtec wasn't kicking in. Had to rev to higher rpm's to hit cruising speed, and had me thinking all sorts of things from final drive swap to a retune.
Finally had our tame racing drivers Dhilan Sabar and Nigel Perera thrash her around a little and see what's what. They both concurred on the fact that it was fuel starvation. Idle fuel pressure was 42 psi, which was normal but when throttled it dropped to the low 30's, instead of spiking. So the Perera-Sabar forum advised to:
1. Replace fuel filter, which was probably stock, and now pushing 15 years with our golden nectar
2. Service the vtec solenoid.
All done, replaced with a Nissan filter used on the track cars by the local boys, under 1600/-
And she shot out of the garage like a bat out of hell! Holy crap the difference!! Throttled fuel pressure reading now blips up to 60psi, and my god that makes a world of a difference tho. Still I want a more pronounced vtec engagement. Should speak to Zackie about it.
