Is it worth it?

Hello all! I have an 89 Mclaren w/ 60K. It has the following done to it...

KYB gas-adjust rear shocks
sub frame connectors
strut tower brace
steeda tri-ax shifter
aluminum drive shaft
rear disc brakes
power slot rotors in front
msd dist.
taylor 10mm wires
bbk chrome fender mount intake
larger maf
bbk throttlebody w/ egr spacer
fireball coil
black magic extreme elec. fan
under drive pulleys
140amp alternator
flowmaster 3 chamber catback
brand new 4:10's
brand new clutch
brand new fuel pump (factory LPH)
17" 5 spokes

I have a Trickflow streetheat upper & lower intake w/ phenolic spacer just sitting in my garage.
My question is: Is it worth bolting on considering my current setup?

Thanks in advance!!!
 
Back in 87, I put a factory 87 intake on my stock 86 Mustang, and noticed the difference, not huge, but plenty enough to notice. You'll also notice the difference from a set of 1.7 roller rockers, though your gas mileage will go down about 1 mpg. Aftermarket heads make a huge difference.
 
Thanks y"all. What about a "chip" ?

I have a "chip". From Diablo Tuners for my mustang, it cost $200. This is what I have my car tuned with, based on the factory computer. I have my tune loaded onto the "chip". That being said, a chip and tune together should be over $600.00.

With your mods, you don't need a tune. At this point, you would be throwing money done the drain. Wait until, you do heads, or a blower.
