Okay i have about $800 i am about to spend on my 99z. Just trying to decide where to go next. My mods are slp lid, magnaflow cat-back, ls6 manifold, and some free mods. THese may be the last things I am going to do to my ls1 becuase I may have to sell it. I want them all to be bolt-ons nothing that I will have to take someplace to do. I have done all the work on my car and I plan to keep it that way.

Ok these are my setups that I am thinking about.
1. MAC LT headers with offroad y-pipe $569 and slp bolt on subframe connectors $239.
2. Diablosport predator $325 used granatelli maf $300 and pro 5.0 shifter $160.
3. super chips micro max tuner $400 and ssra $199.

Has any heard of the micro max tuner they claim 32 rwhp on ls1s and 17 ft-lbs of torque. click on the link to find out. Let me know what u guys think.

Thanks,
Adam

 

I have the Superchips programmer. I've been doing a lot of things with my car so it's hard to tell just what I got out of the programming. It's a nice programmer and can read GM error codes. The coolest thing is that now I can run up to almost 7000 before shifting now, makes a big difference.

$400 is aweful high price for it. I paid $325 from http://www.speedunleashed.com/

I think the car feels more responsive and the purchase was well worth it to not bounce off the fuel cut-off redline anymore. Oh and you can disable skip shift using the programmer. They really crammed a lot of options in. I also bought because they are now based out of Central Florida. I can always drive up to the factory for support but haven't needed to.

Longtubes for sure. Forget about the MAF, not going to help much at all, plus its going to mess up any tuning you might try to do. Ported Throttle Body and maybe the Fast Toys Ram Air setup.

 

How about you wait until you know if you are keeping your car. It would be a waste of money if you sell the car after adding these extra mods, because you will not get the money back.

 

i didn't think mac made longtubes...only middies...which will still be a good choice.

forget all the maf and programmers crap...

stick with easier air in, and easier air out:

SSRA for sure, great gains. same gains at slow speeds as the slp cai and FTRA, but at higher speeds becomes a true ramair and has higher gains.

if you wanted longtubes, you could do the pacesetters or Flowtechs for about the same cost.

another good mod is an underdrive pulley, ASP makes a good one. and there are noticable gains on top end.

oh yeah...and definately the shifter and maybe a Proform shift light to really get consistent with shifts

 

I think I might go with the macs with offroad pipes and then either the predator or superchips tuner since the offroad pipes require tuning. I think the predator may be better for cars with headers as the superchips is made mostly for stock cars with intake and cat-back. They do claim 32 rwhp though, but I think if I get the macs I'll go predator which I have seen for 325 shipped. Maybe I'll drop the extra 200 and get the ssra anyway.

 

I would stay away from the Midlengths. Just get Longtubes to start with, they create more power through the entire curve than Midlengths. I know alot of folks who bought them and ended up selling them for longtubes. You don't need a tune after you get headers, sure it may free up a couple (3-5hp maybe). Save that money and get something else.

 

actually...as with every mod...the difference between mids and LT's is debatable.

about a month ago someone posted a back to back dyno test of mids vs long tubes....they dynoed nearly identical +/- 2hp across the band.

if you are worried about clearance issues...there really isn't a noticable loss of power from mids to LT's

and tuning is not "required" with ORP, all it does is program out the rear o2 sensors. and why buy a $350 programmer for that when you can just get a pair of $90 o2 simulators. since you have a m6 you wont even need the programmer for things like shift points and firmness....big waste of $$

lol...."They do claim 32 rwhp though"....thats funny

K&N claims 15hp with a filter, hypertech claims 30+ with thier programmer and how many guys see NO or even a lose of 1/4mi time....lol.

claimed and real world are 2 totally different things.

you have looked at the pacesetter and flowtech LT's correct? $375 for ceramic coated WITH o2 extensions (needed with LTs), and $125ish for the ypipe.
the macs are not ceramic coated...just a thought.

you can not go wrong with headers (you choice...any will help), SSRA and a good shifter

 

Agreed, SLP also claims a six horsepower increase from their fifty dollar(?!) smooth bellows. What an abject lie.

 

Just think about it. If all of the manufacturer claims were true we could add lid, filter, MAF, smooth bellows, ported TB, IAT module, programmer and get 400 RWHP.

 

So true! Like, "Hey Al, I see you just added an SLP exhaust package! Man, now you can make the Kessel Run in just 12 parsecs!!"

 

Someone mentioned a ported throttle body...Carter Edwards at MASC Performance, does the best ones around. Check it out, not bad for 120 bucks!

There is a pic in that thread.

 

I've only heard good things about the macs and its a good deal. But I would feel more comfortable goin with LT's. Is there really that much of a power difference between something like slp and flowtech or is the price difference so much because its slp. I saw the flowtechs for 379, what kind of power gains have people seen from these and what y-pipe should I get with them.

 

Go with option 1. Get pacesetters they get as much power but cost less. Just get a different Y-pipe.

 

Pro 5.0- 125 used
cutout- 25
Pacesetter headers- 400 (i have em and love em)
lid- 75
