This is a request for Experienced Crossfire owners who are qualified to answer these questions. I understand that, in order to gain a substantial improvement in power on my pure stock SRT6, I would need several upgrades: Eurocharge tune, upgraded s/c pulley, exhausts deleting cats, one or more pulley changes, efficient mufflers for cat-delete exhausts, possibly a s/c pulley scatter shield.
Acting on my own limited knowledge, I have already acquired:
1. Code 3 Stainless steel 65 mm s/c pulley(no spacer came with it); Question: a. Can I use the stock spacer for this? b. Is stock spacer .020-.030 thick as required for the 65mm pulley?
2. I ordered two 5" dia. bullet Magnaflow s.s. 21 inch mufflers, 2.5" single inlets and single outlets;
3. N/W catless exhaust system (with plug for A/F meter if used);
None of these have yet been installed, and most have not even arrived yet. I do not want to waste money on parts or even go to hiflow intake manifold or larger 550 injectors unless NECESSARY to prevent catastrophe. I'd rather not have to buy an A/F meter, either, so maybe the dyno tune would obviate the need for the A/F meter. What do you think?

NOW, I need to decide what NECESSARY improvements I need to acquire and install:
A. Idle pulley? Tensioner pulley?
B. stacked pulley system?
C. or s/c pulley scatter shield?
D. N/W Dual CAI?
E. Do I NEED an A/F meter?
F. should I drive 400 miles to Houston to have dyno installation of Eurocharge computer upgrade or just do this by telephone? I believe the dyno tune could produce more h.p., safely, but perhaps not.

Being retired and on fixed income I won't be able to do all this at one time, orall in one month, but with patience I should be able to get the NECESSARY work done in a few months. Thanks.

 

The stock tune is rich. All the mods you've purchased can be installed with the stock tune at minimal risk using 91 or higher octane. I'd recommend taking the trip to Houston for a dyno tune after everything is installed. The email tunes are real close for WOT. I can't complain about the power. It's brilliant actually. Part throttle drivability is untamed on my car. Real touchy. If I could drive to an Eurocharged shop I would do it in a heartbeat.

Thanks, Les. By the way, I think we must have been in the same occupation! [Recovering lawyer after 45 years dealing with that kind of peeps.]
