Hi, the 222/230 Titan 2 cam above is my car. As a note, I have 1.8 rollers with the cam, so its a little bigger than advertised.

Very few tuners have the skill of Spin. He's a true legend on this forum, and worthy of that title. A large part of my engine's design is based on his posts.

Tuning was by far the very hardest part of my build. I started tuning late spring of 2020 - while Covid was in full swing.

I got three different mail-order tuners to help. Two were snake-oil sales men that didn't give a ****. One them was the god-father of LS cam selection on LS1 and this forum. He was the originator of my Frankenstein base tune.

All three never got base tune parameters correct. Almost impossible to tune when basic values are incorrect.

Finally after several posts on the HP tuners forum, an old tuner helped me get basics and some other values correct. The tune they started to settle down. I did all of the street tuning. A good tuner in Fredericksburg VA did the dyno tune.

I've read, talked, and worked with numerous car owners that got a dyno tune that was crap on the street.

When selecting a cam, going above zero degrees overlap can be very dangerous. Read Rodney's (Old Motorhead) post above and his other posts on this forum.

Assuming your tuner is going to spend hours driving around town getting the drivability correct is 99% a bad assumption.

Dyno tunes are quick, a few hours at most. For tuners, time is money. Street tuning unless the owner is willing to pay a small fortune is almost always never going to happen.

So, back to big cams and great tunes, the two are very hard to bring together.

Again, Spin is awsome, his tunes are great. If one used a SpinMonster spec cam, I bet he could give you a 95% tune by just sending you an old tune file he has on disk.

But assuming that if you put in a big cam, that your local tuner will get it dialed in so it drives like stock is a huge assumption. One that likely will go very badly.

Just my two cents.....

​​​@SpinMonster If you're ever in the Washington DC area and have an afternoon, I would welcome your review of my tune. :-)

 

Thank you for the compliments.
My health isn't holding up so I don't travel much anymore. I've traveled big distances in the past to help people without my hand out for anything but lately it just isn't really possible.

 

I have seen 520rwhp a few times and this thread shows the combo of a 230/234 114+2 on an LS3 with trick flow heads making 521rwhp. I didn't sell him the parts and I didn't do the install:

When tuners state their huge overlap cam makes more power everywhere, ask to see chassis dyno proof.
Use a proven combo that drives great due to low overlap. I've seen expensive lessons learned by guys who went ported stock heads with huge overlap. Why go huge overlap to make near the same power?
