I've been reading and trying to learn as much as possible from the forum for quite some time already and since then I've slowly been working on my car and tuning it. Aside from it hanging on the upper RPMS for a few seconds after revving the engine, it idles pretty good.
Thus far I have already read as much info on tuning Speed Density on a Gen3 with boost. I've also already seen the Greg Banish DVD's and may need to view them again as this was about 4 months ago.
However, now I feel like I'm ready to get to the WOT pulls so I can start having fun with it at the track. I took the car out for a ride today so I could get some data for tuning.
Two things I noticed from the start.
1)The car hangs on the upper RPMs for a few second after revving the engine. (I suspect some additional idle tuning is still needed)
2)I tried to launch the car today on the transbrake and it felt seriously underpowered.
3)I got on the heavy foot on an empty street today and the car felt like it had no power!
I suppose its best that I not get on WOT anymore until i get the bigger fuel pump as I dont think the Wally 255 will be good past 7psi even then I may be pushing it with out any meth injection. I plan to switch to E-85 once I tune on 93 octane first and once I get the bigger pump.
I will try to provide as much info as possible on my combination along with logs and tune. I do appreciate everyone's input.
