Think I'll "need" a tune
I have a 90 formula with an LB9. right now it has edelbrock headers, 3" exhuast, and a K&N filter. next month I'll be adding 1.6 rockers arm, pulleys, and I'm gonna play with the air box a little. I know SD doesn't respond to mods like a MAF system, so how much can I get away with before I truly need a tune.

Re: Think I'll "need" a tune
I never touched the chip in my 305.
I bought a hypertech chip and at the track I actually LOST 2 tenths in the 1/8th!!
I was about 400flywheel hp with nitrous.

Re: Think I'll "need" a tune
I think youll be fine with those simple mods. If you did a cam or head work, high flow TPI that kinda stuff you'd "need" a tune.
