221rwjp I assume, you have to account for the 17.5% for manual and upwards of 22% for an auto to get flywheel power and also remember that a dyno is not 100% accurate, they can vary quite a bit (also based on what type of dyno etc etc)

your car stock is around 170rwhp~ so you picked up 50 with the mods you have ~ guestimate of course.

[trickflow211]

I should have way more then 50 shouldn't I?...

[trickflow211]

How much would a tune give me? And I have the stock intake manifold, should I wait to get that to tune it? Or can I tune it now and then...? And what else can I do for hp?

[rnorth]

what type dyno was it?

[trickflow211]

Idk...it was at a gm race shop.

[Benjytps]

not too bad for what you have but you are still missing some critical mods to balance out your combo. You will need to upgrade intake, and exhaust to allow the head cam combo to flow like it should. What size mass air meter are you running?

[silverstangboy]

well at least you got the TB part right, from here I'd look at something other than factory exhaust alot of power on the table there.

what cold air kit and what mass air? 3" 3.5" 4"?

oh and as they say 221 isn't bad, you'll find probably another 20 or more in the tune.
you don't have a chip, so have you bumped timing a little?

you didn't meantion what intake either, a cobra/gt-40 would do you well.

[trickflow211]

I do have full exaust I'm sorry. But I don't know what size air flow I have, and I have stock intake.

[Benjytps]

look at doing an intake swap, find out what meter you are running to make sure it works with your combo and get you a tune. I can help you out with a mail order tune if you like but a dyno tune would be your best option.

[trickflow211]

What kind of chip should I get? And I have a ram air cai idk what size either tho.

[SimplyOrange]

any chip is fine really,one of our guys uses a moets chip on the 5.0 cars and it yeilds great results.but i agree with benjy, do the intake first and make sure the mass air and tb work together and are big enough, then do the tune to tie it all together.

[trickflow211]

Ya thankyou, I'm having a lot of problems with it I got to get fixed 1st. I was thinkn about putting in a torque converter to. Ya? And what else?.

[SimplyOrange]

torque converter would do good, but wont help on the power side. and ummm........nitrous :giggity:

[trickflow211]

Nos is bad for ur engine, I got to many miles...

[SimplyOrange]

not nessicarily if its done right.i have a 125 shot right now. but high mileage doesent help...

[trickflow211]

Ya I got 103...ill wait till I get a new engine. But where can I get this chip? And how do I noe if my maf an tb run good together.

[SimplyOrange]

see what size the maf and tb are and let me know, make sure the maf is calibrated for 24lb injectors, i have a chip in and i can mail it to you with the tune on it, you just plug it into the back of the computer and its ready to go.

[trickflow211]

So u just program the chip to everything I have? How much should that add?.

[trickflow211]

So u just program the chip to everything I have? How much should that add?. How do I noe if its programmed for the 24lb injectors?.

[SimplyOrange]

no definite number but i can ask our guy, and get you a close hp increase

[trickflow211]

Kk thankyou. Well I will keep in touch and when I have money for the chip I will hit u up.

[SimplyOrange]

okay

[bubbafinch]
