mine is being worked on now..i'll give updates as soon as i get it back..

RCZ · 11-02-2010, 04:37 PM

A pinch under 9psi? I thought it was a 8psi pulley?

Fezzik · 11-02-2010, 04:41 PM

Yeah> i have a cheap analog guage. I'm not worried about a pinch under 9. If it was reading 12 then yeah I'd be worried.

RCZ · 11-02-2010, 04:47 PM

Lets rephrase. Thats probably wrong, but could you plug your car into the dyno when you do the runs?

weiboy718 · 11-02-2010, 05:44 PM

My hks camp II read 8.5psi of boost

RCZ · 11-02-2010, 05:45 PM

Fezzik, how cold is it in chicago? might be why...

Fezzik · 11-02-2010, 06:36 PM

yeah its mid 50s i did some runs in low 40s.. maybe

DannyGT · 11-02-2010, 11:01 PM

Its dropping into the 30's and 40's here in Jersey at night and so far no problems with the cold/hot start. My car is always garaged though so we'll see tomorrow. I'm planning on really opening her up tomorrow and sending the logs of some beastly 4th gear pulls to Sam, hopefully he can further tailor the tune to my car. I'm eager to squeeze every bit of power out of it. So far though, smooth as butter!

P.S. All this is being done without meth yet. I plan to dyno it first, install meth, dyno again.

Ah sweet!

Well I was raised in Elizabeth, and I'm currently in the Short Hills/Millburn area. Just 15 minutes from Newark airport.

I think this honed/extruded pipe really did the trick as boost definitly has the capability of climbing past 8psi. But its only at 7000rpms+ for me, so its doing whats its supposed too as far as I can tell. Unless I was going to go past 8k I dont see myself ever going past the 8psi mark. Maybe 8.5psi... But i'll be honest, tomorrow will be the day I can give a bit more concrete info as I'll be really letting her loose.

Well I think that answeres some questions since alot of others were wondering if the kit was pushing the PSI that it said it was able to. I found it truely impressive how great of a tuner Sam is that he can do all this with out the car infront of him. Honestly makes me wonder how well my car would perform if it was on his dyno and him adjusting the parameters.
Me and my girl our from the cherryhill area. Good luck bro tomorrow and please keep us updated.

Nice, Danny. Can't wait to get my new intake pipe as well.

He has a base map/tune that works on everyone's car then he makes slight adjustments based on whatever he sees on the logs that you send him. Its more or less the same exact thing as tuning, except it takes a whole lot longer. The answer to your question is "not that much better" although it would be quicker. As an example, say he saw your AFR go too rich from 3000 to 5000rpm, he would go back to your map and take out a little fuel in that rpm range. He would look at the rest of your logs and make whatever tweaks he deems necessary. You get the new map, log a few more runs and he can see which, if any, changes need to be made. Repeat the process until he is happy with the logs and you're happy with the way it drives. Its not as complicated as people make it seem.

Some people actually choose to do it even after they have dyno tuned the car. Dynos can't accurately reproduce real world conditions, so its always a good idea to do some runs out on the road with a logger so you can send the data back to the tuner to verify that everything is working as it did on the dyno.

Its not too complicated but its a nice service that we dont have to do the tuning. Sure it takes longer but that's some cost savings.

Thank you RCZ I wasn't fully sure on how the process worked since I never had my car custom tuned.
