Yes, getting a tune makes every mod worthwhile. [

Lunchbox Delete Accomplished
3804
24
It was a lot harder than expected to keep the hanger on the Lunchbox and fortunately a friend with the right saw was able to do it for me.
I love driving with my windows open and without music because the joy of hearing the downshifts and the pops and backfires makes it a joy to rev match.
Would getting a tune make my CAI and Lunchbox delete even more worthwhile, I wonder?
The car feels undoubtedly more punchy without the box and I wonder if there may have been a boost in power...though during engine braking the car doesn't slow down quite as much without the Lunchbox.
Sometimes my revs hang sometimes they don't. The other thing I have noticed is the car lurches on 1-2 shifts under hard acceleration.
If others, who are driving de-PZEV cars with similar mods and have a tune, could chime in - I'd appreciate it very much.

I would consult Tom (1TurboFocus) about that question; due to the insane amount of bolt-ons I have (including IM and now 3" MAF) I run 93 oct for safety. In your case though (with the couple of minor bolt-ons you have) I believe Tom can provide you a tune that only requires 87 and will still offer better driveability. Just PM him to be sure.

No, but to take advantage of a reflash, get a 91-93 octane tune= it is worth it.[thumb]

Premium fuel allows a tune w/ more spark advance, etc.

More spark means more powaaah but with my limited mods...would that make a difference compared to an intake manifold + header?
Also...does a TB really make a difference and if I remember correctly... You even have an under drive pulley etc

Yes a tune that allows you to benefit from 93oct will help out. Cossie knockoff manifold is definitely worth it (even on the 2.0s despite popular belief), the stock plastic unit I am not a fan of. TB does net gains albeit very small ones iirc, you will want one if you get an upgraded IM. I ditched my plastic TB because it kept getting stuck during cold weather. Pulley does not do anything for these cars, only reason I have a WP pulley is just for looks under the hood plus I bought it off a friend for cheap. Stage 2 cams and upgraded valvetrain are in my future.

Still would be an improvement over 87 once you are tuned. I got my HKS 2.36" catback for 90 bux of Craigslist. Sometimes you can stumble on deals.

Karmakc, since your running a 23, I'd do a bsd plug. One of the cheapest effective mods you can do a on 23. Your going to notice a t/b on the onramps. Do a sri/cai & add a tune. Tell your tuner to delete the rear o2 sensor & egr.

Rear O2 is just for measuring cat efficiency. Deleting it negates bogus "cat inefficiency" check engine codes...and allows you to delete the cat down the road if you chose to do so.

These work for a 2.0 or if not Then what would be good?
@OP do you have any pics of your operation?

I don't have pictures but I can tell you it was a PITA because I intended to keep the original hangar and exhaust exit. Cutting it away from the Lunchbox was made more difficult because the weld for the hangar was on the box and not on the tube.
That said, love the note and pops...I'm having a hard time staying off the throttle and blipping often for rev matched downshifts are now the norm - especially at low speeds

Thanks for the response...I have no plans to de-cat my ride...so probably won't go that route.
As for a BSD...maybe - but since I already have a cfm rear trans mount...I don't know if I can handle any more low rpm vibrations.

BSD is only on the 2.3's, and the new ST's.
Pulling it gives you almost 20lb. off the front of the car, and an extra quart in the pan. Revs quicker without spinning a lot of that weight.
(BSD = balance shaft delete. Aftermarket plug setup to seal off the oil feed to the balance shaft assy.)

Ooohkay. Googled lunchbox delete. For some reason I thought it was under the hood and was that large box the air traveled through from the filter.. So this is actually at the tail end of the exhaust. I have multiple tools capable of completing a mod such as this and may do it at some point.

Do you have a PZEV car? If you do..you may want to get rid of the air filter box - it is quite restrictive.
