Just got dyno`d. They didn`t want to tune it because of previous problem with a Caddy computer almost crashing it...They did say that vettes with similar setups were getting 450 - 470 rwhp.

Baseline (with B&B x-pipe) 331rwhp/333rwt
+maggie,B&B headers, magnuson tune 390rwhp/379rwt

Maggie putting out 5 lbs. (should be good for +/_ 100hp?)

looks like a typical dyno sheet, I`ll try to post it when I get access to a scanner.

Has anyone had an '06 maggie dyno tune?

I may have to get a CAI, lord knows I could use the +5hp.

Thought I was through with the mod bug...

Go with a 2.8 pulley and a tune and you'll see 430-440 at the wheels :thumbsup:

Remember too tha the LS2, though bigger displacement, is running higher compression than the LS6. So your boost will be slightly lower. You just need a good dyno tune and you'll be there.

MP112, 112H or 122HH?

MP112, 112H or 122HH?

No idea, none of the paperwork I have says anything about which one I have...

Truck motors and Maggies don't mix...:stirpot:

Your numbers look ok to me.

What size pulley?

What size pulley?

2.9 stamped on the front pulley

My first dyno was 389 rwhp with a good tune on a stingy dyno,no cai,no headers,3.0 pulley with only corsa exh.Like it or not your close to where you should be.

Magnuson is now including a 2.9 pulley, not a 2.8 pulley, on their CTS-V units. Not sure why.

Personally, I'd recommend a 2.6 pulley and an awesome tune. You can even *mail order* both of them on this forum. You'll be so happy you won't give a shiat what the dyno sheet says.

2.9 stamped on the front pulley

Fax the pages to Magnason and tell them that is unacceptable. They advertise rwhp gains much higher than that &, in my mind, it's "their" problem to fix. They will probably send a smaller pulley.

5lbs seems way too low and your increase in HP is rather pathetic for a supercharger. You probably want to be hanging around 7 lbs.

:yeah:

But remember, Luna leaves his last name out on this forum.

Everywhere else he's Mr. Tic, so watch out.

It seems like deja vu from two years ago with the early adopters. This time it for a LS2. Could be the tune, could be the pulley, could be the IC circuit, could be the dyno, could be _______.

That's why we call it MOD HELL. :lildevil:
