(supercharged) do i need a tune?

[dmw319]

i have a 00 camaro with 84k on the stock motor and stock fuel system (new fuel filter). i supercharged it about 120 miles ago, and my car is sputtering when i go WOT. everyone on ls1tech.com says i need a tune. but shouldnt my car be fine without tuning for the s/c?? i plan on getting a tune anyways, but i want my car to run right first.. then get a dyno, then have TSP tune my car again.

ideas?

p.s. its a 6psi ribbed pulley. 103" belt, powerdyne blower, etc.

you can never hurt getting at tune. i think it will unleash so much more from the car just by smoothing everything out

Re: (supercharged) do i need a tune?

i agree i just know everything can work fine without a tune first.

im guessing the fuel system would help but were and how much does a tune cost????

Re: (supercharged) do i need a tune?

50 bucks.

50 bucks.

Thats an awesome deal!!!! My custom tune cost me $575. Mmainly cuz the shop had to buy licensing for a 3.8 from HP tuners. When I go back for another tune it will be cheaper, but still not $50.

I would deff get it tuned even though its a little rough right now. The tuner told me that cars with centrifugal sc's are picky and can sometimes need a lot of tuning depending on the application. Yes, you are right, it shouldnt NEED a tune just yet, but like the tuner told me, some cars are just picky like that.

Also, if I were you, I wouldnt get it tuned by a shop then tuned again by TSP. I would just leave it alone after the first tune. Just my .02

no, TSP is tuning it haha.

the 50 dollars covers the shipping to and from TSP. they do unlimited retunes

Ohhhhhhh! I gotcha. I thought you were getting a dyno tune! Cool, disregard what I said previously posted then.

Re: (supercharged) do i need a tune?

i would still get a dyno tune...TSp is only gonna be so accurate on a F/I car because its all guessing....a dyno tune is the real thing. No screw ups

Re: (supercharged) do i need a tune?

yea but its $450 versus $50.

This is how I look at it
Dyno tune
One shot $350-450

Mail order tune
$125+ shipping your old pcm=$135

1 hour dyno time w/ wideband=$125

Ship back computer to dial in a/f, spark & whatever else is needed=$40

1 hour dyno time w/ wideband to verify final a/f=$125

Total on Mail tune=$425

And in the end its still a mail tune

don't forget to add in the cost of a decent scan tool so you can verify if your having kr or whatever else. A mail tune is rarely a one shot deal especially on a FI vehicle.
