dyno n20 tunning need some suggestions and hp input

[lsxTAlemy]

hey guys i have 99 ta mods on sig i have the edelbrock already on and i am going to hit it with a 150, its going to be a speed density tune. now the tuner told me to get one step leaner and one step richer for the fuel side for tuning. what jets would i have to get. what can i expect out of the car hp wise i don't know if its going to be a mustang dyno or a dyno jet im basically full bolt on's and some extras like the th350 and suspension.

did your tuner aso tell you to get some colder plugs? my guess is if you are going by a companys chart it will take a little more than 1 step leaner on the fuel side to get the tune cleaned up.

[lsxTAlemy]

yea he told me tr6's gaped at .30. that's what i have cuz i was already hitting it with 100 tr6's gaped .35 untuned and stock intake. now i will be tuned and tr6's gaped .30 new intake and 150 hit.

you NEED to throw the tr6's inthe trash and run some ngk 7's

[lsxTAlemy]

i told him the same thing and he told me he has about 7 car on 150 with the tr6's he says at .30 they will be fine

NGK: Br7ef for the 150 my friend tr6s are a little hot and you want a non projected tip

[lsxTAlemy]

hows that victor jr working for u i put mine in without tuning and the car feels like a dog hope the tuning makes some difference

[Pete91]

I'm sure all these are going to tell you br7efs. I know plenty of people may tell you tr6's are fine beca but from what I've learned so far is you should really be using a BR style plug not TR. .... Correct me if I'm wrong

[lsxTAlemy]

where can i get the br7's. iv tried looking at advanced auto parts but no luck. i was going to drop them in but couldn't find them. i bought two sets of tr6's just in case..

[lsxTAlemy]

i cant correct if i don't know lol. i did what my tuner told me simply because iv seen the cars hes tuned and there flying. i was going to get the br's but cant find them so that's why i went tr6. now he told me this morning to get two jets leaner and richer than suggested but i don't know how far. i asked him and he told me one step leaner and one step richer left me dumb.

hey man whats going on? nitrous outlet sell them, as well as speed inc, ws6store might have them as well. and if i were you ill check with murray's they probably have them and are local.

Go to napa if there is one around. Search the web. Lucky me there is a Napa around the block from my garage I paid $1.80 per plug I bought 40 only catch is it took a day or 2. I called up the local speed shop prior to that it was 2.99 a plug, and if I bought 50-60 he was gonna do 2.50 per. Shop around look for a napa though. BTW stock# is 3346

javier1730 hey bro i didn't really want to order them murray's taxes for everything man there prices are higher then the rest...

Pete91 i have a couple napa's around here 15 min away thanks for the stock num imma see how it go with the tr6's and see how they do if anything then go with the br's ...

javier1730 went stock fuel pressure regulator everything up and running now going to put her on the dyno see what she dose

[lsxTAlemy]

anyone know what i should expect for hp?

[javier1730]

Nice man, the set up looks killer...did you figure out the nitrous issues you had?

[lsxTAlemy]

i didn't have a nitrous issue. when i put everything back together the car was tripping cuz i had 3 leaking injectors. im guessing that was my problem at the track couple months ago. plus i think the motor was also starving for air with the ls1 intake .

Find a new tuner!

The vic jr will feel slower because it will lose low end tq and make stall tighter.
Spray it out of the hole and it will loosen up.

Do some seaching, lots of threads about plugs and jetting in this section.

[lsxTAlemy]

no offense or anything. but i went threw 4 different tuners with my brothers car and this guy was the only guy around here that got the car to idle run and shift properly.

thanks for the advice on the intake at the end of the day that was what i needed the car was sideways till the 60ft shooting off the hole running 9 psi on the nittos

Not going to offend me because he doesnt know anything about tuning N20. Do yourself a favor, Keep looking or let him tune everything but the N20 and do that yourself.
Now is the time to learn while your still on a small shot.

Put the #7 plug in it.

Nitto's suck.
