I've been trying to find out which one of the CAI's that do not require a tune actually works and delivers what it promises. I've narrowed it down to 3: BBK, Granatelli and C&L with the no tune option. I know that the best way is to get one with a tune but thats not in the cards right now,but I will get a tune eventually. I just want to find out what I can get right now and make sure I won't hurt my engine while but still get some decent power gains. I appreciate any advice I can get, thanks in advance

 

Go with an Airaid/Roush. This intake has a removable sleeve that makes the MAF area a lot larger (great with a tune). Don’t know much about the BBK or C&L, but can tell you don’t go with a GMS with its reprogrammed MAF. The reason is that when you get a tune you will have to remove their MAF and jumper wire. A lot of money for nothing.

Just my $0.02

 

Been running the GMS set-up for six months, really woke up the engine. No problems, no issues, runs great. I would recommend it, can get a used one for about 200.00 saw it listed in the "for sale" area a month or so ago. Do a search in that thread. All check corral.net and ebay! Good Luck.

 

I had the GMS and was very satisfied. I ended up wanting more and went with the JLT/SCT tune, but for a none-tune CAI, go with GMS

 

For a no tune CAI, I think the GMS is the way to go. I have solid gains that you can really feel, and if you ever want to do more, all you have to do is put you stock MAF back in and get a tune, and realize even more gains. So for me, that makes it a plus, and not a disadvantage as bad monkeys mentions above.

 

SAL, if you're eventual plans include tuning upgrades ? I totally agree with Bad Monkey's recommendation regarding the GMS in which he posted is absolutely 100% accurate..With that said, I would highly recommend either the C&L with the new removable no-tune sleeve option or the Airaid/Roush intakes as both are very excellent choices for both non-tune applications and for those who plan on tuning upgrades down the road as well..

 

So in the meantime, the re-calibrated MAF and jumper harness become completely useless due to the fact that neither can be used with computer re-tuning.. Meanwhile the funds wasted on those components which are now gathering dust could have been used towards cold air intakes such as the Airaid and C&L in which each provide both tuning and non-tuning options without requiring the additional use nor purchase for such un-necessary components in the first place ! Therefore not only is the GMS a very huge disadvantage under this scenario but is also a complete waste of money as well IMHO.

 

For those that like their “no-tune” GMS intake, ask Doug at Bama what he thinks of them.

Believe me, I did a lot of research before going the route I did and the GMS just does not make dollars and cents if you plane to do a tune in the future.

 

The age old debate continues... lol. I can only report my own personal experience, and it was positive with the GMS, however, do yourself a favor and get a CAI with tune. You'll ultimately wish that you had and save some money in the process.

 

Agreed

 

I'm an Airaid fan myself

 

Here's my rant concerning the GMS ! for those who don't ever plan on doing a computer re-flash ? I'd definitely rank it as probably the best CAI that doesn't require any re-tuning of the PCM..However for those who plan on tuning upgrades down the road ? the supplied MAF and jumper harness cannot be used with a tuner/programming device in which the tuning files are both written and based exclusively upon the stock MAF settings only ! Therefore you're now stuck with some useless re-calibrated MAF and jumper harness just sitting there gathering dust somewhere in either the basement or garage

 

The GMS no tune intake has seen AFRs in the 17s up top end for their no tune option. That's MORE than detrementally lean. Just my own personal opinion... the only no-tune I would trust is C&L, end of story. In that situation, it doesn't cost a dime to take out the insert, and run a tune. Just my 2 cents...

 

I agree with Tillman. I had the GMS and it was runnging m 16's when dyno'd. I had to get dyno tune the GMS. I would recommend that anyone that has the GMS get a dyno check. Just my opinion. You will never know your A/F is off unless it is checked. I never had a engine check light even though it was running in the 16's.

 

I wouldn't even bother with a cai without a tune you probably won't even notice a difference and like others stated you will lean it out.

 

I don't believe there really is a "no tune" CAI.
I went with the K&N CAI because of it being closer to the same cfm as stock (and I got it cheap from another member).
After running it for a couple thousand miles,the computer had the car running rich (12 to 11). I have heard of others who actually tested it finding the same thing.
Just bite the bullet and get a big cfm CAI and a tune and be done with it.

 

I'm totally satisfied with my GMS CAI for the reason you stated in origianl thread, no tune CAI.

 

Tillman is right. A sustained A/F ratio in the 17's is detrimental. VERY likley will result in burned valves if left for any period of time.

 

Not sure here, but don't they run funny when thwey run lean? Like actually lose performance?

 

Yes if it's excessively lean performance will be hurt. Can also lead to overheating.
