HPT newbie

I am by far not an expert, but I am installing a gmpp asa cam that is a 112 lsa and I don't think I am good enough to tune it so I think I am going to have it dyno tuned, I just hope I can find a place to do it around here okc,ok. I will definately pass on anything I learn along the way, also any knowledge I get from the dyno shop.

Oh yeah almost forgot check out Yank converters for a tow converter that is where I got mine and they are great and very knowledgeable and very friendly

Thanks for the help. I'll check out the converters. Keep me posted on what you find out on your tune. Thanks

Here's a tip: with any cam similar to the gm asa cam (like jon@np has), sd tune it. it'll be a lot more stable.
also, i'm a big believer in tuning out mods, but with such a big cam, or any cam, it's ok to drill a hole in the throttle body. it'll stabilize the idle, keep it from surging, help the a/c load and a cleaner startup, just like we all did in the old days lol.
1/8" hole works well with the gm asa cam, as a start.

also, that cam doesn't make any vacuum, it idles around 70kpa, so a assist vac helps a lot!

thanks for the advise. By SD tune I assume you mean speed density, sorry im really new to tuning. So turn the MAF off, or leave it on but tune based off of MAP values? Sorry if its a dumb question

that's just my opinion on sd tuning, others will have theirs, but i like sd tuning, imo it runs smoother, reacts better and more control over fueling.

yes, set maf hz fail to "0", that will force the pcm into sd mode.
you'll physically need the maf until you install an iat sensor, since it's housed in the maf, the pcm must have the iat.

from there, tune the ve table, but be sure the pe table is setup right.
