Question for Miniram owners
I'read somewhere that installing Miniram or converted LT1 intake
on L-98 that uses stock ECM can cause problems.
It looks like problems are with air distribution inside the plenum,
and this causes front cylinders running rich.
Does anybody here that uses miniram now something more
abut this?
I'm considering switching to miniram (from superram) and I wouldn't
like to get into those kind of problems.

I do believe the issue was corrected with the miniram II or III though, I can't remember which one. I have the MR III on my car and all my plugs look uniform. I've been on those plugs for 20K now.

I have to disagree with part of your statement. Yes TPIS can lower the price. I'm sure that they profit greatly from each unit they sell. From a performance standpoint, on my car it out performed the SuperRam. Dragstrip times went from 12.00@113 to 11.81@115 with the change.
People say that the SuperRam builds great torque but in my application I lost my second gear pull.
I now have the MiniRam bolted on my 406 coupled with a solid roller cam. No 1/4 mile times but sotp on the street the car is an absolute animal.
Spark plugs 5,6,7&8 tend to run rich. This is mainly an idle and very light throttle problem. I am able to overcome this by feeding air from my throttle body port into the vacuum port located closet to the back 4 cylinders.

that wasn't the question from the OT...........however, we appreciate your opinion anyway.........
a custom PROM is essential with the mini; I have run the Edelbrock base/runners, and this is by far the best intake; hands down........I recommend a steeper gear as well, I run 3.73's and the acceleration is incredible all through the RPM range.......
can't comment on the rich issue; not much of a problem for me.....

This is a good question that I will ask a friend drag racing an 89 with the "full" TPIS setup on it. He is using the Mini Ram, TPIS ported OEM heads, TPIS ZZ9 cam, TPIS cold air intake, Hooker headers and 4K stall converter...all on the original shortblock without work...and is running 11.2's at over 120 in the 1/4 and drives from NY to NJ to the track.

As to "richer in the front cylinders," if you look at the plugs you will notice as you go toward the rear cylinders they become progressively darker. This tells me richer, and has been debated, however, w/out a 02 sensor on each cylinder it could be either fuel or air (02). Most importantly it does not stop them from operating ok, it is just not the most efficient design IMO.
This can also be resolved if one had a more elaborate aftermarket ECM/fuel controller that allows for control of the BPW on each cylinder combined with an 02 on each. Cost would be around 2k+....before I do that I will do a sheet metal intake from mercelli.
my.02
I considered using the IAC air to be distributed better inside the intake/plenum to to do this, but I would like to see a pic of your resolve...if you don't mind.

I'm not trying to say you're wrong, but to those with MAF cars, you will not need a tune the day you put the MR on. You can even add 50 cubes, a bigger cam, more injector, and new heads!! It won't be perfect but don't let a tune hold you back.
