When is a tune absolutely needed?

AlexRaymond19 · 02-17-2013, 08:41 AM

I have done the searching, and found out that you don't really need a tune for any of the bolt on's. But i have never seen anyone do all the bolt on's in one go. I just finished momentum headers, test pipes, FI CBE, already had G3's. My question is should i wait to put the motordyne manifold on until right before i get it tuned? I just don't want to do any damage to the engine if it makes it run too lean you know? So whats the scoop? Am i good to go, or what?

How much driving are you going to do before you get the manifold?

AlexRaymond19 · 02-17-2013, 09:59 AM

I have it now. Just debating on throwing it on or not. My apointment is mid march. Maybe 1000 miles worst case between now and then

Those manifolds don't make ANY more power and in some cases lose power my suggestion is sell the manifold and get a tune asap.

I'm interested to know this too.

Im really not interested in peak hp. What good is it anyway? I am interested in the torque increases throughout the curve that this unit seems to produce.

Well then sell the manifold and use the money to pay for your tune.

B/c if you tune your car with this manifold then change back to the OEM manifold you will need a retune I'm just trying to save you time and money.

2 of my friends had that manifold on and it was removed while the cars was still on the dyno.

.........I lost 2whp on the top end and picked up damn near 10whp and 16tq at 4000 with the manifold......Best damn decision I ever made. Talk to SS_Firehawk. He sold his and he regretted it very quickly and purchased another one a month later. Your top end suffers minimally while your midrange gets a huge kick in the ***. If you don't understand power curves and you think the manifold sucks, then go ahead and avoid getting one of the best power gains for our vehicle. I mean peak horsepower from 7300 to 7500 is much better then a power increase from 3500 to 7000. Even still my car pulls all the way till 8k. Hell i make my peak power at 8k still lol

Im just wondering about the no tune at first. Im not going to blow my engine with all those mods at once will I?

No

I had a 3 month fist fight with my manifold before I came to my conclusion. Sum it up, something else was wrong with my car that was losing power, not the manifold. I say put it on, it should run safely without tuning, but I gained 99% of the top end power back and much more mid range post tuning. It's on the first page of my build thread. I'm about to go back and bold/increase font size of my review topics. I'm interested to see if it helps with your rasp too. Not that your car sounds bad, I had 3 eargasms in 30 seconds. It's a 60 min job, just need some deep sockets and hex's.

Looks like everyones already hit the nail on the head!

Reset the ecu to have it relearn your fuel curves. wont be perfect but itll help. none of the bolt ons we do force us to need a tune. it helps with gains and of course yiur car will run smoother. without a tune, your car just wont run at full potential but not enough is being changed to cause harm without it.
