Thread: Could use some suggestions.

i was the latter guy 4.3º kr with headers 1.95 rockers, and a 3.4. i tuned that out with dhp tho.

to further prove my point. on my 2000 GTP i have a 3inch downpipe , zzp powerlog , 9 inch cone intake , AL 104 plugs. overkill tuned pcm . just put a 3.4 SC pulley on today . i seen as high as 8* of KR.
another member, burbman has the very same setup on his 2001 GTP , but he has the zzp pcm and he is seeing less than 2* of kr.

you can buy a dhp tuner set up for 250. and learn to tune. lots of us here use dhp too. maybe more DHP users then the hp tuners.

Im seeing that DHP is no longer in business, I'd prefer to go that route since it's a ton cheaper and doesn't have the pay to use bit. Does DHP have the kind of access to do everything necessary?

@ 04lss: I'm assuming low 14's high 13's, maybe mid 13's at best..?

@ the gurus: So, will I need a wideband AF gauge just for the tuning, or is this something I'm going to have to constantly monitor and mess with? If all else fails I'll try and find someone on these boards that's within a moderately reasonable drive of me and pay them to borrow theirs if I can get away with using it once.

Anyone in the gulf coast region within a couple hours of Pensacola? lol

So an AF ratio gauge, knock sensor, and the tuner, is there anything else I'd be stupid not to get?

BTW, are the SLP knock offs of similar quality to the SLPs?

a lot of us run speed daddy headers, 200 shipped. cant beat em really for the price.

tuning not a one and done type thing. best if its done over a few days time, as you need to let things learn before you scan and re adjust things.

i use the torque app for daily eye ball scanning. nice and cheap, and the dhp for data logged scans.

dont need a wideband but its nice to know for sure what your a/f really is. you can hook it up to the dhp unit and scan with it too.

Ok, so I did some more reading and I guess what I'm currently looking at, for now, is:

SD headers
1.90 rockers
CAI
genV blower
N* TB
modular pulley system
aeroforce interceptor gauge + wideband o2 sensor
tuner
plugs and pulley determined by tune, assuming 3.4 and 104s

1. do the SD headers go to the cat or will i still need to delete the Ubend/buy a downpipe?
2. what all will I need to make the N* TB work?
3. When people are talking LIM, is it just a gasket replacement?
4. Anything I'm missing, either to lower KR or fill this build or anything i have that's superfluous?

what exactly is it that needs to be done to the lower intake manifold? What I gathered from reading around was replacing the gasket, is that correct?

As for the N*, I remember reading something about an ls7(?) MAF, and that I can port the blower housing so that the TB fits without the adapter plate?

Would upgrading the motor mounts be a good idea?

SDs come with the downpipe so that takes care of the ubend.

Lim = lower intake manifold.. Most either had or have those plastic gaskets go bad on them and leak so it's preventive maintenance to go ahead and change them for the aluminum style ones.

Your off to a good start

truth is, it can do more then then HP tuners can. you can use tiny tuner, its a bin editor program. has files unlocked that no one else has. like to kill a cat test for the 01 up cars. make a car with out perf shift have it in the pcm now working with a button you need to add.

hp tuners is kinda like aol was, it holds your hand and has pretty graphs and stuff lol the end result is they both get the job done. HP is probably more user friendly tho.

vet never got his hp tuner synced up, lol dhp is rather easy once your told wtf to do, or you can pull your hair out. ive helped a number of guys set them up here. got screen shots and stuff t help out.

the only support you get is off forums with active dhp users. and bills drop box of gold https://www.dropbox.com/sh/npa8brtuzoq3qps/jqYuBP0cv- dhp software, tiny tuner, bins from almost years supported, tuner manuals and so on.

and he is a caveman lol last i heard it was still not running, dont know wtf he was doing over there. think he even offered to sell it with the turbo kits and stuff.
