Just tuned to stage 3...doesn't feel any different

I was previously running stage 1 93 (Cobb ots map) I didn't really feel much of a difference going from stock to stage 1. I finally got my downpipe and IC on a week ago and tuned to stage 3 93 (Cobb ots) last night. I don't notice any difference at all. Are the gains really that minimal? Or maybe I just need a custom tune?

I don't know a ton about cars, so don't get super technical with me lol. My mechanic friend installs all my parts for me for free.

I did the same thing, went Cobb OTS stage 1 to 3. Stage 1 had a big change over stock, but going to stage 3 had almost no change. I was really disappointed, since I just spent a bunch of money on speed parts to get to stage 3.

I ordered a flash tune from Stratified, I couldn't be happier! Huge change from the Cobb tunes, car felt like it got a good bump in HP and torque.

Thanks for the feedback guys! Just wanted to make sure I wasn't missing something lol. I know there's quite a few good tunes out there that I've seen on the forum. I'll have to look into all of them and see which will be best.

One other weird thing I noticed. Usually when I fill my tank it says 430 miles to E, since the stage 3 flash, it now says 530 miles to E. Why is that?

The reflash resets all your mpg averages so the computer is going off a default number. Happens to me every time I reflash.

I finished installing the Cobb Stage 3 last Wednesday with their ots tune. I was also a bit underwhelmed, ordered a stratified tune for the car that day for pump gas (CA so just 91) and holy shit it really woke the car up, without a doubt the best 50 dollars I have spent on this car so far.

I dont know if it really makes any more power, but throttle response and drive ability are better across the board, my dad drove it and said it was a rocket ship compared to the last time he drove it (stage 1).

Thinking about ordering a second slot for an e30 tune since a station down the street from me sells boost juice

This is something I've hopelessly tried to explain to the fine folks at reddit/fiestaST. I went from stage 0 to stage 1 and thought 'hmm okay, thats a bit more fun', then went to stage 3 and thought 'did i forget to flash to stage 3???? what a waste!'. In any case, at least you're now prepped to go bigger turbo!

It needs a flash tune, from what I have read the Cobb OTS tunes are super conservative, they are painting with a broad brush as to not blow up anyone's car. Spend a couple of bucks on a Stratified or other flashtune, you will not be disappointed.

Another silly question, I don't hit anywhere near 20 boost psi until I'm slamming it on the on ramp to the freeway in 5th-6th gear. I assume this is normal? I normally only get 10 or less when in lower gears.

Not normal 3 and 4 gear wot pull should reach 22-23 psi. You may have a boost leak.

In my experience that is not normal.
I would see 20-24 psi in every gear.
You should be able to feel a good difference between stage 1 and stage 3.
It is possible you have a boost leak. Check the clamps on the pressurized plumbing.

Check the intercooler hose on your passenger side, that generally sees the most pressure, they are loose from the factory. Grab a flashlight and a size 7mm wrench or socket (I believe) and tighten that hose up a bit. Both of my house came almost completely off a year ago.

I bought the Depo charge kit with my Depo intercooler. I had my very talented mechanical friend do the install, but I will double check all the clamps

I usually only see 19-20 psi on Cobb stage 2 map. When I had a stratified flash tune it would regularly see 25psi.

Same here with crap boost psi. 19.70 highest I have hit one cobb stage 1 and 2. Just did an intercooler install all hoses tight. I think I might buy a set of t clamps though not sure of sizes needed. I have a flash tune from stratified but waiting till the dp is on. Too damn hot lately and im a bit afraid of snapping a dp stud. I daily the car 130 miles a day. 71k on the clock.

I found a boost leak at my stock BOV last week when the car wouldnt idle consistently coming off boost (no tune or performance parts). Got a warranty replacement while I overthink which BOV I want. Since youve taken your BOV off at least once to get the Boomba piece on, its worth a check.

Those stock diverter valves are trash I am surprised I have not heard of more of them failing. I probably wont touch mine until I go with a different turbo though. Looking at the MRX.
