Well ive got a point now where ive done some boltons to my car and just wondering if a tune is worth spending the money on and get some results. Just curious as to what people have gained over a stock tuned pcm with boltons vs a tune. What can i expect? Anyone have any files they might be able to send me and get my buddy to flash my pcm?

Pacesetter LTs with Air & Egr
3" catted Y
Borla Catback with QTP Cutout
Ram Air
A/c delete
4.10s

 

I guess youre trying to stay emissions ok, either way get a tune it helps alot.

I remeber when i did a ls6 intake longtubes and a lid on my z28 it was nice, but after a tune holy hell was it better.

 

Tune will wake it up and make it run more efficient

 

Absolutely get a good tune.

 

dont have numbers to back it up but it was a night and day difference after the tune with mods in sig below.

 

Hell ya get it tunes especially if you put a gear in there. YOu will need the tune.

 

For sure get a tune. I got one after my LT install and the car runs so much smoother.

 

I know if it will make a difference in some way but i was just curious as to how much power the tune made you over a stock tune. I know in the LS world a tune can make up some serious power but i know the LT is alot harder. Just wanted some feedback what people have noticed/gained after tunning for bolton mods.

Keep em coming!

 

Irrelevant.

If you change anything on your engine that affects the fuel mixture, spark or the movement of air in or out of your engine, then you need a tune. You'll need a to change the tune for those 4.10's as well.

 

I picked up a mph and about 8rwhp from a bolt on tune...do it

 

Was this a mail order or dyno tune?

 

def get the tune you should feel a slight diff in the seat of the pants dyno

 

tune for sure. i picked up 20hp on my bone stock truck from a good tune.
plus then your speedo will work

 

but even an lt1 will benefit a lot from a good tune. good excuse too dynotune as well then you know your numbers

 

after i did my longtubes and ory.... i got it tuned. picked up about 30hp and bout 25 torque. all i have is full exhaust, CAI, 255 fuel pump and that basically it. mine was dynoed tuned though. id say it is def worth it.

 

i had bolt ons similar to yours last year and even with a hypertech tune i went from 13.9s to 13.60 so i would say to get the tune.. even if it is a mail order or hypertech.. then you can adjust your speedo and so forth..

 

Tune was the cheapest "bolt on" mod it felt like it did at least as much as headers.

 

Much more can be had out of a tune. My car still runs a little rich on the stock tune and I'm waiting on more mods to get the tune.

If it helps, I ran 13 flat in the 1/4 at about 2300 or so DA on Ebay headers, ory, no air/egr, 3.73's, 3600 stall, and some ET Street Radials

 

I've been driving mine around for months with my mods without a tune and I can tell there is alot more power to be had. It falls on its face from 1500 to 3000 rpms which is ridiculous. I know my car well enough to expect 25-30 horses from a good tune, comparatively from when it was well running at stock to running like crap with mods.

 

stock motor trans rearend and stock headers had the car tuned for a 125 shot and went 12.20 so im always gettin a tune after doing ****
