I'm switching my catback from magna flow to SLP loudmouth 2. I also installed a ls6 manifold and did free ram air mod. Do I need a retune? Anybody have before/after #'s after a retune with these mods to see If retune is worth it?thx

With the intake I think you should get it retuned

Maybe get a cam too before you get it tuned?

Just want to do Bolton's due to the miles. To get the right cam I would need a converter . which means I would have to get tranny rebuild(miles).

How many miles?

ironmikektm525

129k.

BEAns_99

Damm in i the only one that has a 190k car lol
I just installed a 4000 stall and it seems very smooth with no tune yet...planing on my H/C or just cam some time next month

definite retune for cold air/intake get a tuner that is willing to keep customer base and go to him so he might give you discounts for retunes. mine does

Lol installed a converter with 190 k with no tranny rebuild? How's your car run with that many miles? I thought I had a lot of miles lol. Yeah shop I deal with retunes for 150. I've just read that ls6 doesn't really require retune ? I need every HP I can get. So if you guys think a retune is worth it I will def get it! Shop recommends 160 stat so I'd have to get fans tunned anyways. What you think on the 160? I've read mixed reviews on the lower stat? Shop I deal with is a reputable shop so I'm pretty sure they know what there talking about

Jaja i use to drive my car to work thats why it has lots of miles lol more of highway not city

BEAns_99

Out of the Tx state

So it still runs strong? What 1/4 times?

BEAns_99

Yeah it does i was at 13.00 with Ls6 intake LT and Volant cold air...i need to get it retuned now but its been raining this past days...i hope it clears up for tomarrow night if not im not going to have any new numbers for it and im leaving sunday back to work! Now in my truck jajaja
Btw my car 1999 WS6

ironmikektm525

That's a good time for those mods. That's with the converter also correct? I have full bolt ons and my best time is 13.0. That's without ls6\k&n\ free ram air mod on stock tires

BEAns_99

Noup just those mods...i just did the install like umm monday i think lol and i was planing on tuning it today but its raining and going to the strip on friday to get the new times

BEAns_99

What car do you have?

ironmikektm525

I assume you have full exhaust seeing you have LT's.have to step out for awhile. Everyone feel free to add there input! Thx

BEAns_99

Oh yes i do but i got duals now...had the y pipe and stock muffler with the 13.00 pass

i hate to assume anything, does the car have the stock factory tune or a mail order? or a shop dyno tune? if stock i'd get a tune. if already tuned then just an intake or muffler isnt that big a change imo.

Op youll be fine without a tune until you do more mods, put that money into a converter and cam then get a retune.
